Despite all the alarmist rhetoric (even on the MSNBC-“Russiagate”-conspiratorial left), neither Russia, China nor any other nuclear-armed adversaries are actually bent on world conquest. That’s right, all the hysteria and close calls and nuclear bluffs are for nothing. They’re unnecessary and unhinged. Not only are these “adversaries” not out for global empire, they’re also not irrationally suicidal—which you’d have to be to send a nuke flying at an American target. What makes these powers dangerous is their (justified) feeling of military encirclement by the United States. They fear for the survival of their regimes (not an absurd sentiment given what happened to the Taliban, Saddam Hussein and Muammar al-Qaddafi recently), which makes them likely to act like cornered, wounded animals. It’s best to calm the rhetoric and not provoke these folks.
