Enough is enough, it is time for a no fly zone and tell Putin if he sends planes out we will shoot them down. If he threatens us with war, well, we will send in troops from all of NATO. If he rattles his nukes, we will put our on high alert and rattle ours back. I had always been against a war with Russia, but enough is enough.
You've always been against war with Russia. In contrast, on a certain level I'd welcome it. I always felt Russia needed a good beating, allied occupation, and crushed into becoming a peace nation (not unlike Germany and Japan).
But after some deep reflection of recent, I now believe Putin believes what he threatens. Whatever belief the West had concerning Putin as being rational and shrewd, but never reckless, has evaporated. When he says if Russia loses, he will take the world with it, I believe it.
And, to be frank, NATO has badly blundered in getting rid of most of its tactical nuclear weapons. Russia has about 8 to 10 times as many as all the allied nations combined. They can selectively eliminate hundreds of smaller battlefield targets and have well over a 1200 to spare. Nato has 150 to 200 tactical nukes, all of which need delivered by vulnerable bombes. By definition a counter strike is going to be significantly smaller.
In other words, NATO has eliminated proportional response and the escalation ladder. If Russia used tactical weapons NATO will either stand down or use strategic weapons, huge nukes normally reserved to wipe out cities. That will likely trigger all out nuke war.
So no, a no-fly zone of any serious consequence is too risky.
