Isn’t a no fly zone also seen itself as a declaration of war????
Like the no fly zone over Iraq?
It would certainly seem to be problematic. I don’t suppose you would have to be in a war, but it would certainly be a confrontation that could lead to one in minutes.
There’s no way I would urge Trump to try to implement one in Syria. It would set up a direct confrontation that we don’t want. I know I don’t.
