But whether he's serious or not about a claim really comes down to whether someone likes it or not. Regardless, I'd argue that's a really poor way to lead.
He's also very sensitive to public opinion of him, and he knows public opinion is against military conflict. People are sick of it.
So war is the complete antithesis of everything he's ever demonstrably cared about. That's a pretty solid piece of evidence that lets you distinguish what seems reasonable, but that gets conveniently ignored by people that let their feelings about him influence their judgment.

I don't like it, but I can't deny that he's made it work more often than expected. Possibly with some negative downstream effects we haven't seen yet. Time will tell.
Oh please.
