You mean the Russians are stupid. Even one of the former Russian generals has mentioned how stupid it was to go invade Ukraine a month before it actually started.Because Russia has not been completely cornered yet. Unfortunately US is likely to let that happen. I have to say, Americans are stupid. They are betting their country's future on other country's rationality and endurance. And the country has a history that burnt their own capital Moscow to defeat Napoleon and sacrificed millions lives to defeat Hitler.
I wonder what Americans have gone through after the cold war. Which makes them to lose the sense of danger.
