I don't like Trump at all, but I'm not blind to history. He likes building things, particularly with his name on it. Even with Gaza his inclination is to build something in that completely devastated area.
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 think there's more going on with the war than just he's anti-war, but I can kind of see this argument. But if we take it as true, it would seem that he's bad at working towards the things he professes to want. He either doesn't understand them or he pushes to get the fastest result without thought as to whether that would be the best.
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.
