Smartest things U.S.A. ever did:

Two-term limit on the president. I wish we would do something similar for Congress.

No prime minister, so no one could pull the switcheroo that Putin just did to get around Russia's term limits.

Clear separation of powers among the 3 branches (at all levels of gov't).

Clear subordination of the military and law enforcement to the civilian authorities (at all levels of gov't).

Clear separation between military and law enforcement.
