The idea that Trump was strongly opposed to the war in Ukraine was always an exaggerated lib fantasy/scaremongering. Trump bragged about being the one to send them weapons before the war, while Obama only sent them, "pillows and blankets."

When he was insufficiently deferential to the notion that US foreign policy is driven by benevolence, libs lost their shit over it and leapt at the opportunity to attack him for not being patriotic enough and being a "foreign asset," rather than criticizing him from any kind of leftist position. Trump was happy to not disavow this fantasy, because it was a fucking stupid and self-defeating line of attack that helped him immensely by allowing him to distance himself from failed lib foreign policy. Without even having to really do or say anything he was easily able to triangulate to appeal to all sorts of alternative foreign policy perspectives, because the libs were so confident that their position was objectively correct and anyone who disagreed for any reason was a Bad Person so they massively overcommitted to their position.

Of course, this sort of the thing is par for the course. Even when American politicians say that they'll be anti-war, it's a lie. Because they can just do that with no consequence, and the military-industrial complex has no shortage of bribe money. What's been happening in recent years is that they don't even bother to lie anymore. Like Trump technically lied saying he would "end the conflict on day 1" but that was obviously ridiculous bravado that didn't even say what he'd do to end it.

This is just a reversion to the mean. He's an American politician, and like every other American politician, he's a servent of Khorne who will always seek to spread blood and death and collect skulls for the skull throne, because that's what they fucking do. We will never be given the option to vote for anything different.
