The difficult task of Obama to convince Congress on the agreement for the Iranian nuclear issue.

After many efforts to reach agreement on the Iranian nuclear issue remains the obstacle of the approval of the US Congress. That achieved by Obama is only a part of the final result, intended, however, to be reached by June 30. The agreement between the US president and the parliament has a right of inspection on the negotiations. The difficulties are well known: the Republican majority in Congress, where the party is known aversion to Tehran, but also from the Democratic doubts are relevant. The Secretary of State, John Kerry, one of the principal architects of the success of the negotiation of Lausanne, said he was confident about the ability to persuade Obama to Congress. In reality, the task is not easy and it seems a possible defeat, as well as deprive Obama of achieving a central objective in its foreign policy agenda, would risk to clear the validity of the agreements. For more in Iran are not sure internal approval due to the presence of even so much aversion to the United States. This uncertainty makes it less important to the diplomatic success in Lausanne and causes new concern for the final signature expected by June 30. The final act, in fact, the negotiations will be based in Lausanne and the agreements reached will be virtually only one being finalized and an official of what was already agreed. Although the US is not the only party in Iran nuclear talks in Tehran, being seated at the negotiating table even China, France, the UK, Russia and Germany, it is clear that a failure to ratify the parliament the US would make invalid the 'agreement reached. The hostility present in the US Congress to Iran and to the results of the negotiation is based not only on the hostility to the country of Iran, on the fear of handing in a legal manner in Tehran the chance to increase his expertise on atomic energy to enable it to become a military nuclear power and endanger not only the regional order but also the world. The pressure exerted by Israel, very in tune with the Republican Party have led to a still greater opposition to the results of the agreement, as well as the diplomatic situation that has been created with the greatest Arab ally of the US, Saudi Arabia, came to threaten to take the path of becoming a nuclear power to balance the power of Iran. If the reassurances of Tehran, who secured the desire to produce nuclear energy for civilian purposes, will not have been sufficient is difficult to predict what will decide the outcome of the Congress. If the first impression is of an opposition regardless, political, a more careful analysis can not take into account how widespread the fear of a nuclear Iran with the social and political fabric of the United States. On this level, the perception is that you are not given enough value to the feelings of the American population, focusing only on the outcome of the negotiations. What has been lacking is a progression parallel negotiations with an operation of sincere conviction of the US company, for years used to identify Iran, perhaps as the worst enemy of the nation. Essentially Obama has divided the approach to the Iranian nuclear issue, choosing to invest more resources in advance to the negotiating table; but now a similar effort should be made even within their own country to confirm at the state level that achieved in the negotiations. Any failure could endanger the laborious approach reached the situation and report back to the periods of mutual dislike. If this event were to occur it would be difficult to give credit to Tehran to Washington, especially for the backlash inside of a company that sees the signing of the Treaty as a means to overcome the sanctions regime. At that point, any possibility of comparison, also the military could become possible.
