Either party will argue against what the other is doing, while they do it, but it's what happens as the parties swap leadership that makes it clear what the party actually dislikes.

They don't discontinue everything the other party implemented, even when it's easy to do so, and that's the true indicator that the party is okay with something, regardless of the partisan complaints made when it was initially implemented.

I don't think so. What's described isn't one party attacking another for positions they supposedly support. Neither of the mainstream parties supported the "end of the American Empire" - that's something you really only heard from paleo-socialists, anarchists and contrarians regurgitating Cold War Soviet propaganda.
