I hope you don't actually believe that USAID helped lives, it's literally a propaganda arm of the government directly intervening in the politics of other countries and being a covert operation for murder and financing dictatorships. That Americans think that sacking it costs "millions of African's lives" is the pinnacle of comedy.
I think I'd rather trust medical experts (The Lancet) and their assessment vs your statement that implied USAID didn't save lives.
