I wasn’t familiar with USAID so I checked their site out and this is how they describe themselves on their front page (emphasis in original):

USAID is the world's premier international development agency and a catalytic actor driving development results. USAID's work advances U.S. national security and economic prosperity, demonstrates American generosity, and promotes a path to recipient self-reliance and resilience.

They literally, openly state the US imperialism is their first and foremost goal. Fuck this goddam evil country.
