"Iran is now the most critical player to watch." No Kidding. Iran has been for a long time. Actually, Pakistan also, but let's not confuse the issue.
"Iran is weakening in the region and is becoming heavily constrained at home," Really? I disagree. It is the U.S. that is weakening in the region. And I do not agree with Iran being "heavily constrained at home." Is he referring to the regimes control of the government of Iran? I don't see any problem there for the current government there either. I think that he refers to what he claims is less revenue for the Iranian government because of the sanctions. I believe Iran is like our dear President in at least one way: I don't see him or Iran CHANGING. They try to make you change.
