Unless Russian mothers do to Putin in Ukraine what they did to Gorbachev in Afghanistan.This is a war. Nothing more and nothing less. Such attacks are par the course. Remember when the Black Sea fleet was destroyed? This is no different.
Right now, it is a protracted war with neither side really gaining much usable advantage except destroying themselves.
The trick is to keep them from destroying everyone else. Right now, at least three other countries are helping the Russians...while the equipment destroyed may not be replaced the same, they will be replaced nonetheless.
This is not going to end without one side obliterating the other.
