How what worked out? None of them dared to invade their neighbors when Trump was in office. Calling them friends is meaningless, actions speak louder than words.
Maybe you should look at the reports out there. Putin was waiting for last admin to pull out of NATO. That was not happening under Biden. He wasn't going to wait another 4 years to see if a coward was back in office.
Last admin stabbed the Afghans in the back, tried to pull out of NATO, tried to pull troops out of Germany, call our hero's who fought in foreign wars suckers and our war hero's losers. I am sure Putin was shacking in his boots.
Putin never invaded when I didn't have a SW CC. Just got one and he invaded. Thats how dumb the logic is without looking at the facts.
Now the facts are we are seeing the strongest sanctions in history that are destroying the Russian economy and the ruble.
