I thought part of Trump's campaign was that he'd distance the US from foreign conflicts and not get involved so much. Is he trying to renege on every single thing he campaigned on?

I think this one is less of a Trump flip-flop in particular. It seems that US presidents just can’t defy these things, even when their whole point is being an outsider. The pressures and propaganda a president is subject to must hit substantially different. Or, if you will, the realities they have to face. Obama ran on closing Gitmo and even that he couldn’t do in two terms (which seems especially absurd in light of Trump’s evident power to just make things happen unilaterally). I’m no Trump supporter but I do still think he was in a unique position to ignore this sort of stuff. Pity it wasn’t enough.
