The money is a fraction of what the United States has contributed in the past. The United States on Monday announced a $2 billion pledge for U.N. humanitarian aid as President Donald Trump’s administration continues to slash U.S. foreign assistance and warns United Nations agencies to “adapt, shrink or die” in a time of new financial realities.The money is a small fraction of what the U.S. has contributed in the past but reflects what the administration believes is a generous amount that will maintain the United States’ status as the world’s largest humanitarian donor.The pledge creates an umbrella fund from which money will be doled out to individual agencies and priorities, a key part of U.S. demands for drastic changes across the world body that have alarmed many humanitarian workers and led to severe reductions in programs and services.The $2 billion is only a sliver of traditional U.S. humanitarian funding for U.N.-backed programs, which has run as high as $17 billion annually in recent years, according to U.N. data. U.S. officials say only $8-$10 billion of that has been in voluntary contributions. The United States also pays billions in annual dues related to its U.N. membership.Critics say the Western aid cutbacks have been shortsighted, driven millions toward hunger, displacement or disease, and harmed U.S. soft power around the world.
