I understand that the U.S. and a few other NATO countries are considering sending F-16's to Ukraine and some of the countries are already training pilots. This is NOT good news for anyone. Russia made comments that if they do this, they will consider an act of war and will respond. With all of the NATO countries having to join in when the $hit hits the fan, what do you think Putin's next move will be? I have a pretty good idea.
Let's be clear about this. Putin cannot take on all of NATO, so his options will be limited if he wishes to prevail. On the other hand, his Army may have had enough and just quit. The soldiers know that to continue fighting all of NATO, (if from the ground), many, many will be killed. I doubt if they can whip 31 countries. (I know, 32, if we count Sweden.)
