> [...]a no-fly zone that no one will enforce given it would mean engaging with, guess what, the air force. Oh, and starting a nuclear war at the same time. A thought experiment: - if Putin is not insane and wants to live and enjoy his lifestyle (but plays his role to frighten everyone) - that means he is unlikely to use nukes - which means it might be practical to establish a no-flight zone, etc If you believe he is insane, however, the West has nothing else to do than to let him grab whatever he wants (Estonia, maybe?). This is a dead end for NATO.
