Should NATO enforce a no fly zone over Kyiv?

22. That would still result in war

You don't get to assassinate the leader of a nuclear power and just get away with it. It doesn't matter how much of dick he is, the Russian military and Russian government is not just going to let that happen. There is no way they will let the precedent stand that the West can kill Russian leadership with no consequence whenever it feels like it. If Putin get taken out it needs to be from within, not from the outside. Also, how are the Russians going to know its a conventional warhead? Nuclear tipped cruise missiles have been in existence since the 1960's. I'm definitely not a radar expert, but I can't see a way that radar could determine what type of warhead the missile carried considering the missile itself looks exactly the same regardless of its payload. And I wouldn't expect the Russians to just wait and see, particularly if it were heading towards Putin and other Russian leadership. Decapitation strikes can be seen as immediately preceding a first strike.
