Two games: Domestic and Foreign
Domestic 'gain' is fiscal + political + transparency. USAID was pass-through where taxpayer dollars flowed to NGOs and contractors whose missions aligned with whatever administration or congressional bloc was in power – but with enough layers of separation to obscure the nature of the spending.
Foreign 'gain' is a move away from liberal internationalism to transactional bilateralism/resetting expectations wrt American largesse. We were being outbid everywhere anyway, and the org was ineffectively doing something DoS should be doing.
