Yes, we should have prepared Ukraine for that eventuality. But we then armed them much better, and they were able to turn back most of Russia's attacks when Russia decided to take the whole of Ukraine. Why should NATO help us in Iran, Iran did not attack us, we attacked them. Iran needed and needs to be taken to task for their support of terrorism, but not in a way that only strengthens the present regime. And that is exactly what we and Isreal have done, strengthened the present regime. Now the people of Iran are more behind the regime than against it, because we bombed the hell out of many civilian targets. A complete FUBAR.
