Since the dissolution of the USSR NATO states have been involved in one conflict, the war in Afghanistan. While it was terrible and now mostly regarded as a failure, it was not internationally panned in the wake of 9/11 and since its opponent was the Taliban no one lost any sleep over it. The war in Iraq however was only a joint US-British issue, so not a NATO conflict but fought by NATO members. It was much less popular globally, and triggered the largest global protest in history and further aggression from Islamic terrorist organizations. The United States also provided a no-fly zone in Libya during the Arab Spring, bombing campaigns in Yemen, bombing campaigns in Pakistan, very small intervention in Somalia, and small amounts of troops and advisors in Syria.
Now, and pay close attention here because this is important, it all fucking sucked. Fuck the States. Fuck Bush-Cheney. Fuck Hillary Clinton. Fuck Obama. Fuck Raytheon and Boeing. Fuck BP and Exxon. Fuck NATO. Fuck it all.
See? Condemning bad stuff isn't hard, so why don't you try that with the war Russia just started? Or do you have to both-sides that too, very fine people on both sides of the unilateral invasion of Ukraine?
Shadow edit, threw in a fuck NATO, got distracted by all the blood on GW's hands for a second there.
