The answer to any and all of those 'questions' is simply that if Russia hadn't fired a bullet, nothing would have happened and everything would be fine and dandy even for they themselves, so that was a useless post if I ever seen one. Trying to be clever but actually not really.
Anyway, I'm just now reading that after the US greenlight, my country (Netherlands) is going to supply F16 fighter jets (number unknown) to Ukraine at least together with Denmark.
I guess we can expect a Russian threat of dropping a nuclear bomb on Amsterdam or the Rotterdam port anytime now.
