Okay, so people online keep complaining about how the invasion lead to the deaths of millions there, how it destroyed a nation, how it has created ISIS and lead to the mass migration that Europe is suffering from etc. etc. etc. but this is something I never understood, why didn't the world save Iraq? Why didn't the world stop America from invading it? And I don't mean stop it by protesting but actually stop it, like blockading America, cutting ties with it, sending troops to Iraq, isolating the US and threaten it with invasion?
