In my mind 2 things will happen. If Putin keeps hitting slush he will continue, if he hits steel he may stop and think twice. There will come a time very soon when we will have to put that steel in place, then we will no doubt find out for sure if Putins threats are real. But for sure we are dealing with a very grumpy old man here who can at any time completely lose his temper in a split second, and it only takes a moment of temper to release the worst.
