By early 1762, the alliance of France, Austria, and Russia was choking the life out of plucky little Prussia. Russian troops were occupying large areas of the country. Only a miracle, it seemed, could save Frederick the Great this time.
He got one. Empress Elizabeth died and was succeeded by Tsar Peter III, who was an extreme fanboy of Frederick’s. He immediately pulled Russia out of the war. Prussia would live to fight another day, and the rest is history.
You have to think Putin is aware of the analogy to his own position with Trump and Ukraine. Of course, he may think Trump’s victory is largely his own doing, but if he does, he’s wrong; the misguided American voter and the price of eggs did the job for him.
