Who knows? What the heck does it matter? You really think Putin is going to be bombing NYC from the cockpit of one their bombers? For the last 60 years MAD has been the policy of both nations. You ought to spend some and familiarize yourself with Cold War I. You really should have taken the time before you started cheerleading for Cold War II.
I remember the duck and cover drills.
I also remember being terrified when Saddam started throwing missiles at Israel.
Absolutely NOTHING I have seen of late reassures me we aren’t heading for some serious ugliness.
