I don’t know who thinks otherwise but NATO has taken the right decision by not imposing No-fly zone against russia, at least as of now.
The reason is simply that it may escalate war further in europe as well. Who can guarantee that Russia would not have attacked other nations with nuclear weapons??
It would be great if these two nations (Ukraine and Russia) negotiate ASAP, otherwise a full-fledged world war is not far away. And remember, nobody is going to survive it.
