No-fly-zone for Ukraine now

Close Ukraine skies. Work with NATO and Ukraine to declare a no-fly-zone over Ukraine. Give Ukraine aircraft and support staff. I know this puts the U.S. in direct conflict with Putin. But that is the better option than waiting for him to commit war crimes throughout Europe and Asia because we are afraid. The U.S. should not give in to the mafioso extortion racket of Putin. "Nice EU you've got there, shame if someone nuked it..." Establish a no-fly zone. Defend it. Lead NATO to defend Europe.
