"Officials from the United States and other countries have questioned the legality of the strikes."
Look, this is getting tiring. You have no idea what the people in this country went through and they might as well see it as a "good thing". I think the same applies to Iran, an intervention by the US could be the best thing that ever happened in these countries, so the "legality" issue doesn't quite sound warranted in my opinion.
a chinese intervention to overthrow trump i think would also be quite welcomed, but still not the best thing to do
Ends justify the means is bad policy in any context.
Im not sure we want the president to be going around bypassing congress in regards to the military. I would prefer a congress that took back its power from the executive.
