The Ukraine/Europe vs Russia crisis.

Zelensky and Europe have started a war they cannot win. The 1962 Cuba Missile Crisis, a diplomatic confrontation between the United States and the Soviet Union, was on the verge of nuclear war. This did not serve as a lesson to them, they foolishly wanted to put NATO bases next to Russia. It did not earn him any warning, like a glass against the cauldron.
