Uh... no. It's an abandonment of any kind of strategy at all. You can be completely opposed to realpolitik and still believe in what USAID is doing (or the other things the Trump administration is getting rid of, like funding the WHO or other international efforts). For instance, an idealist would support USAID work to promote democratic institutions and conflict resolution.

It's not like they're saying "in the past we've played chess using only king's pawn openings and now we're going to switch to using queen's pawns openings", it's "we don't like this game so we're going to kick over the table and stomp off".
