How will the US aid freeze affect countries around the world?

For decades, the United States has been the largest single donor of aid globally. Last year it provided more than 40 percent of the UN's humanitarian aid budget. But now most foreign assistance through the state department has been frozen for 90 days, with only emergency food programmes and military aid to Israel and Egypt exempted. The aid supports initiatives ranging from health and education to security and conflict. So what could be the effects of America's freeze on aid, both for itself, and other nations? And how will it reshape Washington's relations with the world?
