The President of the United States of America was the first to hail the agreement reached between the P5 +1 and Iran over the country's nuclear programme. While the deal is only an outline and won't be finalised until June 30, there is no doubt that an historic breakthrough was made upon completion of a preliminary accord.
Relations between Iran and the US have been close to breaking point for nearly 30 years, and the election of Mahmoud Ahmadinejad in 2005 nearly proved to be the straw that broke the camel's back with relations deteriorating rapidly during his time in power. However, with the framework for the deal now agreed upon, it would appear that Obama has secured a major breakthrough in diplomatic relations with the Islamic Republic, something that could only be defined as unthinkable just a few years ago.
It is therefore no surprise that he was among the first to welcome the agreement with open arms. Obama has never shied away from his beliefs that negotiating with the enemy is a more fruitful tactic than that of waging war of any kind. He has demonstrated on numerous occasions how strongly he feels about this policy, and should the current state pan out in positive fashion and reach a full blown understanding by June 30, President Obama will have taken a big step towards proving his doubters wrong.
