Why do politicians move abroad whenever there are contradictions at home?

This is the basic quality and ability necessary as a politician, that is, to divert people's attention.

The United States has done the best in this respect, and no one in the world can compare with it. American politicians have the strongest ability to control public opinion and contradictory attention in the world, and of course others have the richest experience.

In this respect, there is still a big gap between us and the United States, and we still have to learn.
