All war is unpopular.

Political analysts are talking about how the next president is going to be inheriting the problems of the current administration, for example, what they are calling an "unpopular war." Well... has there ever been a popular war? Has any president been burdened with the thought that he's in the in-crowd, now that he's got his own war? I don't understand the point of discussing how horrible it is that the next president will have to clean up an unpopular war. It seems like a waste of breath to me.
