Political Memes

This is the case now, but in case of a global-scale war Europe will absolutely be involved in opposition to America, even if as I said they're likely to not send troops. Therefore, supporting America would be helping one geopolitical semi-rival* wear down more dedicated geopolitical rivals while pulling the semi-rival to their side, overall strengthening Russia's geopolitical position. Also in the case of war (unless it's a classic Europe + US against China scenario, but that's looking less likely now) US-Europe relations would necessarily deteriorate, lessening the incentive for America to stand with Europe against Russia. It's not like Russia and America are directly competing for anything important now that Syria is mostly settled; Russia's ambitions are mostly a threat to Europe, not America, so if and only if the US-Europe alliance breaks down better relationships with Russia would start making sense. Yes it'd be bad for billionaires, but that's the thing about fascism: The fascist dictator can do whatever the hell he wants and shoot anyone who disagrees. Capitalists tend to (not unjustifiably) count on the dictator to be a benevolent (to them) dictator, but there's no mechanism guaranteeing that benevolence.

*I say semi-rival because, even though Trump is opposing Russia, he's not nearly as dedicated as precedent would suggest, so the rivalry is cooling down.
