Say like when Afghanistan, Iraq or Libya were attacked? All three were justified to a lesser extent. The West were pretty good at war, not so good with the peace side of it. Mistakes were made in all three. Afghanistan should have been in and out with the goal of killing Bin Laden, Iraq they made the mistake of disbanding the army and securing all the weapons, Libya, I really do not understand how they thought things would not devolve. But these were places that, for better or worse, the UN was in general dissagreement (other than China, Russia, North Korea, Iran). But otherwise I do not recall many times a Western country invaded another country in the last 50 years. Yes there was Yugoslavia but that was because of the killing. I do not recall any Western country saying they want to invade the other country and make it a rump state.
