But it could happen. The last time the US boycotted the Olympics, completely thereby missing the whole point, was under Jimmy Carter. And now we have Jimmy Carter to the 10th power. Carter's boycott was followed by a boycott of the Olympics in Los Angeles by Eastern Bloc nations in 1984. They set up their own separate games they called the "Friendship Games".
And Carter's reason for the boycott in 1980? ..... wait for it ..... the Russians had invaded Afghanistan.
“We do not believe any group of men adequate enough or wise enough to operate without scrutiny or without criticism. We know that the only way to avoid error is to detect it, that the only way to detect it is to be free to inquire. We know that in secrecy error undetected will flourish and subvert”. – J Robert Oppenheimer.
