Boston: isolated act or from an organization?

Despite the identification of terrorists that have plagued the Boston Marathon, too many points are still obscure in the story. If the matrix, as it seems, comes from Islamic terrorism in the generic sense of the term, for now do not appear to be involved structured organizations such as Al Qaeda or its emanations, such as the Vilayat Dahestan group that operates in the Caucasus and that could have had contact with bombers, and indeed just that group has denied any involvement in the murder of Boston. For investigators, however, is very important to determine whether the two bombers acted on their full, if they have been part of a sleeper cell of a larger organization and then what are the reasons of the attack or whether, finally, are direct part of a well-defined structure. Knowing this detail is essential to design prevention strategies, in this context, although it is a hypothesis worrying discover that behind the massacre there is an enemy with a well-defined identity, it could facilitate the selection of countermeasures. However, if the attack was carried out in complete autonomy raises even more disturbing questions on the state of American security and, above all, calls into question the openness of the country wanted from Obama. On the other hand one of the first reactions involved precisely the approach that the U.S. president has given to immigration, especially from open areas considered too close to the Republican Party. Certainly an episode so severe can not change the address with which you dealt with the phenomenon of migration, but certain considerations must still be made. According to reports both brothers perpetrators of the attack were perfectly integrated into American society, which hid malaise, which has not been noticed, and that brought in the determination to carry out the massacre? It is clear that there are dark areas that have matured the decision to strike, provided that it is the fruit of their single action. But the report by Russia made two years before the FBI on his older brother, directs suspicions towards something more complicated, that an attack at home. Tamerlan Tsarnaev had made a trip to the country from which the Russian seemed to come back changed. Despite that American investigators had not found anything relevant on the behavior of the Chechen. It should also be said, on the sidelines of the event, that the cooling of relations between Moscow and Washington has eased mutual cooperation on terrorism, a factor that may have had decisive importance in the light of what happened. One of the analyzes that can provide answers such as to give a direction on the actual matrix of the attack, will be the analysis of explosives, on which there is the strictest confidentiality. These tests may provide links and origin of a potential enemy far greater than just two people. What will be the American reactions to a possible discovery have been the victim of a terrorist organization, rather than an isolated act? If with Bush, there has been a general mobilization in a war also not justified, with Obama this risk should be lower, but once again the U.S. would be required to be involved in a reaction, which would not bring any good.
