"Our" success rate ? The world doesn't revolve around the US, this isn't "our" conflict to win. They have to sort out their own internal cultural and religious conflicts, and they haven't.
Our success rate infers our governments, or collectively NATO member states actions taken in the name of purported humanitarian or democratic reasons. Actions that include overt and covert subversion, corruption, and interference in the affairs of sovereign states.
I wouldn't ever say the same about nations engaged in conflict with one another if those conflicts had not included NATO member states providing assistance in all its forms to one or more parties in said conflict. I don't just say this shit expecting the U.S to take responsibility of the worlds problems, no. I say this shit expecting the U.S and its NATO allies take responsibility for the worlds problems they had a direct hand in helping to bring about.
If you trashed your neighbours house, a third party wouldn't expect your neighbour to pay for the damage and clean up the mess. Instead they would reasonably expect you to pay for the damage and clean it up.
