If you can, recall that a conference to prosecute WW II was held in Tehran. Iran was a vital corridor for supplies delivered to the Russians.
By bringing up 1953, you ignore the fact that things change. You are attempting to insert irrelevancies into the current reality
It’s everything but irrelevant.

The list of repeated “bipartisan” mistakes on our end has perpetually continued up through Obama’s administration. No matter how ugly and ignorant the dog is, when you keep kicking it over and over it will indeed come to hate you. Cause and effect. We need to also address “why” the dog hates us, this is just as important as how dangerous the dog has now become or we will continue to keep repeating these same actions.
