It works both ways. In those times it was advantageous for the Russians to believe we were as crazy as they were. Candlelight Kumbaya vigils for Peace would have only earned their contempt.
Also, having a "Cowboy" elected got the Iranian hostages home, and quickly.
One cannot reason with someone who seriously wants to kill them. That is why negotitations with Iran and Mideast Peace Talks are such a futile self-defeating joke. Our adversaries have only contempt for cheap talk, and properly see it as weakness.
Another factor in the Cold War in our favor, Americans play poker, Russians play chess. War more closely approximates poker because one can never KNOW with certainty all the variables. No matter how much info the Reds gathered, there was always some uncertainty, so they would never call a bluff.
“Candlelight Kumbaya vigils for Peace would have only earned their contempt.”
Just as they do now. Ron Paul are you listening?
