The speech with which the American president Barack Obama has turned to the Arab and Islamic world, the University of al-Azhar in Cairo, has had a huge resonance and a strong emotional impact on many politicians, observers and ordinary citizens in countries Middle East. Undoubtedly - have pointed out some commentators - as Obama has been able to go to the Arabs and Muslims, has been able to tap some important strings. The overall impact is therefore without doubt positive, but concerns have emerged from an analysis of the details. The most important element in the speech (to the point that some have called a "historic turning point") was the closing chapter of the "clash of civilizations" which - if not in words - were

imposed on the facts 'neocon administration of George W. Bush. And 'Now that has all the symbolic value of the speech given by Obama. On the other hand, others have noted that the words expressed by U.S. President could have been uttered by his predecessor George W. Bush, and in fact he had several times stated concepts are not too dissimilar. What up to now distinguishes the two presidents is credibility: to many Arabs, Obama has a credibility infinitely superior to that enjoyed by Bush. But it is this wealth of credibility that the current American president will play very soon, when it inevitably must move from words to deeds. "Be practical." This has prompted a loud voice that many observers have undoubtedly appreciated the new American approach, but noted that doing this climate of reconciliation and renewed optimism will vanish quickly if the talks do not follow radical changes in American foreign policy, and concrete steps to resolve the Arab-Israeli conflict. And it is precisely in terms of concrete issues that the Obama speech is still felt inadequate, and certainly not able to reverse the tragic course that has followed in recent years the Middle East conflict. Many Arab analysts have noted that requiring the "freezing" of Israeli settlements in the West Bank is not sufficient, since only their dismantling will make possible the emergence of a Palestinian state. Others have criticized the U.S. President to have said the rockets fired by Hamas, but he had remained silent on the massacre of civilians consummates in Gaza during the Israeli attack in January. Others have argued that in the absence of a new American approach towards Hamas, which in turn facilitates inter reconciliation is illusory to talk of resumption of the peace process. But there are also those who, in the nuances of the speech of Obama, believed to capture interesting hints for future store openings on the American side. "America does not claim to know what is best for everyone, as we do not want to choose the peaceful outcome of an election," said Obama. Citing this sentence, some were immediately reminded that the Hamas government was democratically elected. So, if it is true that the elements contained in the speech of Cairo are not, in the view of many Arabs, yet sufficient to give new momentum to peace efforts, it is also true, according to others, that Obama may not have yet discovered all its cards. No doubt there will be a strong diplomatic offensive by the Americans, but it remains to be seen whether it will be enough to overcome the enormous obstacles that hinder the practical realization of a solution of two states, both independent and able to survive. As yet are not fully known, the real balance of power within American and attributed to the internal resistance to effective diplomatic offensive. A prime example in this regard, although in a completely different context, is that of Pakistan, where for the moment it seems that economic aid for development of the country have a note in the margins of politics eminently military still adopted by the United States, and not vice versa. A large proportion of the Pakistani press has criticized precisely this ambiguity in the new U.S. administration. When Obama speaks of peace and reconciliation, the tactics the U.S. military continues to be focused on the use of massive drone, pilot less aircraft, which have so far killed only a few militants of al-Qaeda, instead doing the massacre of civilians. In addition, the Pakistani army is pursuing an offensive against the Taliban which has been strongly desired by the Americans, and that resulted in a short time about two million refugees and a humanitarian crisis of alarming proportions.
