That’s what wild weasels are for.
I thought Mrs. Clinton did a reset with our friends the Russians.
Plus I would think that if it came to this, we would have ships off shore and in the air at standoff range launching missiles. The air defense systems cannot stop all of them.
Force them to exhaust their supply then go in, knock out the air defense and now you own the sky. At that point it is over.
Not if smart artillery takes out the S300 sites first. Special forces on the ground can “take care of business” locally electronically as well as with brute force in many varied ways. There is other “stuff” we need not worry much if it comes down to it.
