…and very possibly the biggest, is Ukraine. In the past three years, since the invasion, they provided about $23 billion in direct aid to Ukraine. I found one link indicating the FY24 support was $4-5 billion, out of a total agency budget of $43 billion.
Military funding is through a different channel, but killing/freezing USAID is a way to put a significant hit on US support for Ukraine without it being obvious that’s the goal.
