As questionable as I find this particular action, and its timing, and its motivations, and as much as I dislike Trump and think he's a wicked idiot....I don't think this was something he actually wanted to do. I think he got pushed into it and, in typical Trump fashion, tries to claim credit for what he imagines is a credit-worthy thing. Love this attack or hate it, it doesn't seem very Trumplike to me. His style is to make threats and not carry them out. I think he really wanted two weeks plus to look tough, not to actually carry out risky action that might backfire spectacularly not only in themselves but also for the political consequences to himself. Trump's risk-averse when it comes to his own popularity, isn't he?
I think it was people around him who pushed him into this, and I don't think it was his weirdo crypto Nazi cronies -- they strike me as much more interested domestically than internationally. I think it was remaining Bush-like warhawks who pushed for this now, the "old school" that's still managed to hang in there.
