You're incredibly wrong. Trump's bombing in Syria was universally applauded, and was the only time I've seen criticism of obama from foreign countries.
Second, and I don't expect you to know this being Swedish. America loved it. CNN was practically sucking Trump off. They were beating the war drum disturbingly hard.
Lastly, there is a huge difference between gathering support to take on NK, and giving a shit what the rest of the world thinks (Paris accord, travel ban, etc).
Also, I meant what I said. If it wasn't for America leading on the tough issues, back seat drivers like yourselves would have been massacred long ago.
