The Syrian issue, too long overlooked, could have a far greater impact on the complex system of international relations. The last story concerns the renewed tension between the U.S. and Russia, which seems to be inspired by the gloomy atmosphere of the Cold War. The United States accuses Moscow supplying Damascus with weapons, combat helicopters and anti-aircraft systems, conversely, Russia accuses Washington to do the same with the rebel forces. If both deny their mutual accusations, Moscow, however, admits that he has actually sent air defense systems, which are part of a batch of supplies previously signed the beginning of the ongoing civil war, while the U.S. has only confirmed the dispatch of medical supplies and equipment for radio communications, categorically denying the sending of arms. If it is very difficult, especially now, the truth, the sending of anti-aircraft systems, also confirmed by the Russians, is to be consistent with the strategy of Moscow to prevent the Air Force can bomb the troops Assad. The Russian thought is based on previous cases of Serbia and Libya, where, to wear down the regimes in office has been used air power, through bombings, which were to be targeted, has operated with the aim of undermining the governments in office and in support of ground forces rebels, avoiding the direct use of foreign troops on the ground. Syria also had these plans, tracing a pattern of action now settled. Russia, joined by China, has joined the diplomatic efforts with the veto in the UN Security Council, with the provision of anti-aircraft systems, thereby obtaining from the armor of the Assad regime, even if the agreed actions of the outside the UN umbrella. So if the Russian anti aircraft provide coverage of the Syrian sky, in conjunction with the impossibility of a ground invasion, Assad for the moment remains firmly in place, since the composition of forces in the field can help the rebels, in the best hypotheses, only the maintenance of the conquered areas, in short, a situation of stalemate which, however, plays into the hands of the Syrian dictator, because it enables him to recover precious time to reorganize the systematic conquest of the territories to him far more. The Russian attitude is not new, in the key geostrategic Moscow Syria is an important player, because that nation has hosted the only Russian military base in the Mediterranean and a possible change of leadership of the country could create conditions for a eviction of the former Soviet naval vessels, especially after the behavior of support for Assad held until now by the Russian government. The situation is particularly tense between the U.S. and Russia prevents any progress on the path to peace in Syria and the hardening of positions does not promote the bilateral meetings that were held in the coming days and are now suspended. The greater involvement of Russia in favor of Assad thus risks becoming a dangerous obstacle in resolving the issue and determined that the only possible strategy is a greater involvement of China, to which actions must be made to convince to change their attitude in considering possible alternatives to the now failed peace plan of Annan. A change in attitude would lead Russia to a Chinese diplomatic isolation on the Syrian issue difficult to explain except by the admission, for now always denied, deep interests in Syria, such as to allow the carnage carried out by Assad, a position difficult to sustain for a nation who aspires to resume its role as superpower, in a context that is not what the years of the Cold War.
