Before September 11, 2001, the United States had obligated about eight billion dollars combined to Afghanistan and Ukraine.
In the two and a half decades since, it has obligated more than two hundred and eighty-eight billion to those same two countries
more than thirty-six times as much, adjusted for inflation.
That number is striking on its own. But it raises a sharper question:
did 9/11 change who America helps, how much America spends, or what kind of help America sends or all three?
This project is an attempt to answer that question using seventy-eight years of US foreign aid records from ForeignAssistance.gov,
the official US government database tracking every dollar the country has obligated abroad since 1946.
The story the data tells turns out to be more complicated than a single pivot in 2001, but it is also more dramatic than the dollar totals alone suggest.
The data behind the story
Every figure in this piece comes from ForeignAssistance.gov, a public database maintained by the US Department of State
and USAID that tracks American aid to other countries from 1946 to the present. "Aid" here is a wide category:
it covers vaccinations sent to clinics in Mozambique, food shipped to refugee camps in Jordan, training for Colombian police,
infrastructure loans to Pakistan, and the rifles, radios, and artillery rounds delivered to Ukrainian soldiers since 2022.
All of it gets recorded as a dollar amount, attached to a country, in a fiscal year, and tagged with a sector describing what the money was for.
One quirk of the dataset is worth noting, because it matters for reading the visualizations below.
Aid is tracked at four different stages of a pipeline, and the same dollar can show up under different names depending on where in the process you look.
The four stages are Request, Appropriated, Obligated, and Disbursed. The Request is what the President asks Congress for at the start of the year.
Appropriated is what Congress actually agrees to spend. Obligated is the money the government has formally committed by signing contracts and grant agreements.
And Disbursed is the cash that has actually left the Treasury and arrived at its destination.
Throughout this piece, the numbers reflect Obligations in USD adjusted for inflation (constant 2024).
Obligations sit in the sweet spot of the pipeline: they're a firmer commitment than appropriations since Congress can change its mind about what it appropriated,
but breaking a signed contract is harder. Using constant dollars matters because comparing eras without adjusting would make past commitments seem smaller than
they really were.
Who: a tale of two eras
Between 1946 and 2000, the United States obligated roughly $1.94 trillion in foreign aid, an average of about $35 billion a year.
Between 2001 and 2024 it obligated $1.23 trillion while less in total, which works out to roughly $51 billion a year.
America is spending more per year on aid after 9/11 than before it, even though the headline total looks smaller.
The bubble chart below shows where the money went in each era.
The composition of those bubbles tells a different story in each half. Before 2001, Europe and Eurasia dominated at thirty-two percent of all aid,
a legacy of the Marshall Plan and four decades of Cold War spending on NATO allies and former Soviet states. East Asia and Oceania came second at
twenty-four percent, anchored by Vietnam, South Korea, and Japan. Sub-Saharan Africa sat at the bottom of the list, with less than five percent of the total.
After 2001, the picture inverts. The Middle East and North Africa moves into first place at thirty percent. Sub-Saharan Africa, which was last place in the Cold War era,
rockets to second at twenty-four percent, nearly five times its previous share. Europe and Eurasia drops to fourth, even with Ukraine pulling the region's number back
up after 2022.
A second pattern
Three countries appear in the top fifteen recipients in both eras: Israel, Egypt, and Pakistan.
Israel alone has received more US aid than any other country in either period $211 billion before 2001 and another $100 billion after.
The Israel-Egypt pair traces back to the Camp David Accords of 1978, when the Carter administration brokered the first peace treaty between
Israel and an Arab neighbor and committed the United States to large, that has held across nine administrations.
Pakistan's continuity has a different logic: a Cold War partner during the Soviet-Afghan war in the 1980s, it became a frontline ally again after 2001.
Whatever else changed at the turn of the millennium, these three relationships did not.
Why 2001 was the turning point
The "War on Terror" launched in late 2001 reframed foreign aid as a tool of military strategy in a way it had not been since Vietnam.
Stabilization Operations, counterterrorism financing, and post-conflict reconstruction all became standing budget priorities rather than emergency one-offs.
The final report of the Special Inspector General for Afghanistan Reconstruction, released in December 2025, captured the scale of the experiment:
$148 billion appropriated for Afghan reconstruction alone, $89 billion of it going to security-sector projects, across twenty years.
Iraq absorbed another $105 billion under the same logic. At roughly the same time, President George W. Bush announced the
President's Emergency Plan for AIDS Relief, committing $15 billion over five years to fight HIV/AIDS a program that would grow into the largest commitment by any nation to address a single disease in history.
Regional totals are one way of seeing what changed. A country-by-country view is sharper.
The two maps below shade each country by the total obligations it received in inflation-adjusted dollars;
click between the two eras to compare.
The geography, country by country
Both maps include Obligations and are shaded on a logarithmic color scale, so that small recipients remain visible.
Hover any country for its cumulative total in that era. It is worth noting that pre-2001 obligations were the only part of the pipeline being tracked.
After 2001 · 2001–present
Both maps shaded by total Obligations in inflation-adjusted USD.
Use the layer toggle in the upper-right of the post-2001 map to switch
between Budget Request, Appropriated, Obligations, and Disbursements.
The pre-2001 map looks like a Cold War atlas. The deepest shading sits in Western Europe and in the partners of the containment strategy:
South Korea, South Vietnam, Israel, Egypt, Turkey. The post-2001 map looks like an evening news map.
Afghanistan and Iraq, the two longest American wars of the twenty-first century, are the darkest on the board.
Ukraine, almost invisible before 2001, becomes one of the largest recipients in the dataset on the strength of appropriations made in just three years,
2022 through 2024. Sub-Saharan Africa lights up in a way it never did during the Cold War with a pattern that comes back into focus in the sector breakdown below.
How the shift unfolded, year by year
The era-totals view smooths out a lot. Aid does not arrive in steady annual installments it spikes around specific events.
Press play on the visualization below to watch which countries dominated the regional bubble chart year by year, from 1946 forward.
A few moments are worth pausing on. Iraq's reconstruction spending peaks in 2006 at $14 billion in a single year, then tapers as US troops draw down.
Afghanistan's curve climbs steadily through the 2000s and peaks at $18 billion in 2011 before declining.
There is a long quiet stretch in the late 2010s when no single country dominates.
Then, in 2022, Ukraine appears almost out of nowhere: $22 billion in obligations that year, $50 billion in 2023 being the single largest one-year commitment
to any country in the entire dataset. The first time a European country has held the top spot since the Marshall Plan, according to the Council on Foreign Relations.
What kind of help: from food to firepower
If 9/11 changed who received American aid and how much, it also changed what the aid was for.
ForeignAssistance.gov classifies every dollar by sector: health, agriculture, education, infrastructure, security, and so on.
The chart below tracks the five largest sectors in the post-2001 era over time.
Stabilization Operations and Security Sector Reform is largest category that covers everything from training Afghan police to arming Ukrainian artillery units
dominates the post-2001 era. It accounts for $385 billion in obligations between 2001 and 2024, about a quarter of all foreign aid in that period and nearly
double the next-largest sector. Its peaks line up with the wars it funded: $23 billion in 2008 and again in 2011 (Afghanistan and Iraq),
a long decline through the late 2010s, and a sharp return to $21 billion in 2023 as Ukraine drew down American weapons stockpiles.
The orange line is the more surprising story. HIV/AIDS spending stands at almost nothing in 2001 about $530 million.
By 2004, one year after President Bush announced PEPFAR in his State of the Union, the line has nearly tripled to $3 billion.
By 2008 it is at $6.6 billion and counts as the third-largest sector of US foreign aid. Over the post-2001 period as a whole,
HIV/AIDS alone accounts for $155 billion in obligations and ten percent of American foreign aid.
The two trend lines on the same chart Stabilization Operations and HIV/AIDS are a useful reminder that the post-9/11 era cannot be summarized in one word.
The same two decades that produced the longest wars in American history also produced the most ambitious global health program in the country's history.
What the data shows
The question this piece opened with was whether September 11 changed who the United States helps, how much, or what kind of help it sends.
The answer, from the data, is yes to all three. The geographic center of gravity shifted from Cold War Europe to the Middle East and Sub-Saharan Africa.
Per-year spending went up, even though the twenty-five-year total looks smaller than the fifty-five-year total. And the mix of aid tilted decisively toward security and stabilization, with a major counter-trend in global health.
The "everything changed" framing also doesn't capture the full picture as Israel, Egypt, and Pakistan stayed in the top fifteen in both eras.
The commitments cemented at Camp David in 1978 outlasted the Soviet Union, the Cold War, and the entire War on Terror.
Whatever else the data shows, it shows that some American foreign policy relationships have an inertia of their own
older than the events we usually treat as turning points.
A few things this dataset does not capture, and that would be worth a follow-up project.
It tracks dollars obligated, not outcomes; nothing here speaks to whether the aid actually achieved what it was meant to achieve.
This data covers only the State Department and USAID-administered foreign assistance accounts; Department of Defense channels,
which fund a large share of actual military hardware transfers, sit outside the dataset entirely.
The data answers what changed after 9/11. It does not answer whether the changes worked.
