There is a difference. I don’t see the USA (and by that I mean the general public, not the institutions) is as far gone as Western Europe. We’re not at that stage yet.
But in terms of Ukraine, to intervene is to essentially do the Western European’s job for them. Its their continent, why are we still babysitting these countries? If they want to sit it out, then fine, Vladimir Putin gets what he wants and will be emboldened to advance. They want to fight, go ahead, its about time.
But ideologically I just cannot see how conservatives have a dog in this fight or any preference for the outcome.
Probably not, but ideas like gay marriage seem to get their start in the US so a lot of the Bush-era US vs. EU rhetoric looks flimsy and silly.
We are not just conservatives, we are patriotic Americans, so we do not support our own nation’s mortal enemies. All of your ideological reasons for hating America and western civilization are irrelevant.
