It seems that there is a potential opening in relations with Iran. I commend President Obama for taking the chance that the Iranian president is making an offer that he can and will act on. It is in everyone's interest that the president take the chance that it real. However we must be very careful to guard against the potential that Rahanni cannot or will not follow up and act on his offer. We need to remember that the Iranian Republican Guard has been our active opponent in Iraq, Syria and Lebanon for over 30 years. They aided the Iraqi insurgents by supplying arms and providing a refuge in Iran. They built the bombs that killed hundreds of our troops. They are right now supplying arms to Assad in mass and have been Hezbollah's support in Lebanon. Iran and The Gulf Arab states (Saudi Arabia et al ) are mortal enemies so we need to be careful in our actions. That is balanced with the way they helped us in Afghanistan to topple the Taliban and in the early phases of the second Iraqi War. They have been active allies in some very trying times. The point of all of this is while it is a huge risk I think it is worthwhile as I hope the president has the strength and foresight to manage it. If he does then he will deserve all the congratulations and honors he will reap. If he fails he will be open to criticism not for trying but the way he handles it.
