Yes, the decision to abandon a war is always a political decision. It is, in fact, the political decision that every act in war is directed at getting the enemy to make.
There's this weird and frankly dolschtosslegende-ish trend in America post-Vietnam to characterize American victories in war as military and American losses as “political” as if the two were orthogonal categories, but the only military victory is achieving the desired political end, and if you feel like you were “winning militarily” and didn’t do that, then you just didn’t understand the context of the war and your sense of victory was misplaced.
