Feel good doesn’t feel so good when you realize how much support modern aircraft require. In the best of times it would take many months to set this up. Unless NATO is going to provide it. This would include trained technicians on the ground. It’s not at all like sending a bunch of P40s and a pile of spare parts and a manual and an instructor to train them and letting them get on with it.
Sending the F16s is making an already very complicated logistical situation worse.
