And those aren’t the only numbers that have ballooned. U.S. taxpayers have contributed $4.4 billion in UNRWA since 1948 -- before inflation. In 2012 dollars, total U.S. taxpayer aid to the UNRWA tops $10 billion.
Here's a spreadsheet
of America’s yearly contributions to UNRWA, accompanied by the corresponding amounts in today’s dollars. The contribution data come from a recent Congressional Research Service report and a 1994 book entitled U.S. Official Statements: The Palestinian Refugees, published by the Institute for Palestine Studies. The U.S. Bureau of Labor Statistics’ Consumer Price Index Inflation Calculator determined the value of the U.S. contributions in today’s dollars. All amounts are approximate.
