A No-Fly Zone over Ukraine, are you nuts!?

I am seeing some suggestions that NATO establish a no-fly zone over Ukraine. The implication of that of course is clashes between Russian and NATO warplanes would be inevitable. I cannot think of anything more wrong headed in this whole mess.

I also notice that those who have been making such suggestions are of the generation that were born in the late eighties and beyond. In other words they never had the joy of living with the ever present threat of nuclear war during the Cold War. They never saw, read or heard the extensive commentary of just what a nuclear war would look like and what we could expect in the aftermath. They did not see the increasingly senile Leonid Brezhnev and Ronald Reagan with their fingers on the nuclear trigger. Hell they never saw the movie "The Day After" and had it scare the fucking hell out of them.

I understand the desire to do something to help Ukraine and its people. I share that desire but there has to be limits. By all means provide them with all of the military, financial, intelligence and humanitarian aid possible. By all means sanction the Russian leadership and wealthy back to the stone age and make life a little more difficult for its citizens. 

BUT DO NOT RISK A DIRECT MILITARY CONFRONTATION WITH A NUCLEAR ARMED STATE!!
