Kerry in South East Asia, with the crisis in North Korea in progress.

The visit of John Kerry, the U.S. Secretary of State, in south-east Asia comes in conjunction with the confirmation by the Defense Intelligence Agency, dependent on the Pentagon, which Pyongyang would really be able to miniaturize a nuclear warhead to place it on a rocket. This item was already circulating for quite some thanks to the data reported in the last disputed North Korean nuclear test, which indicated the use of plutonium instead of uranium, a material capable of allowing the construction of a nuclear device in less space. According to some analysts the order of potency that could reach the atomic bomb North Korea would be smaller than about 20 times compared to that used in Hiroshima, but still capable of causing serious damage, in the case of achieving the objective. If the United States have advertised in an official manner, through a government agency, the real presence of the atomic bomb in the arsenal of Pyongyang is to further raise the level of alert and the pressure on China, which continues, apparently to stay in their immobility . Kerry's visit, which coincides with the revelations of the Pentagon, has precisely this purpose: to urge Beijing to a strong action to block the ambitions of the North Korean regime. China has welcomed the change of the Secretary of State, because he saw an obstacle to bilateral relations with the U.S., setting up Hillary Clinton, considered too focused on a vision of where the United States was too central. In contrast, Kerry is considered as a more able to have a broader vision, who can take into account the needs of other countries. Obama, then, not surprisingly, chose this moment for inviting Beijing to take a step that would put an end to the great regional instability. But Kerry will visit in Tokyo and Seoul, as a sign of strong unity in Pyongyang, to dampen the constant threats. In the report, but the news publicized on the nuclear capability of North Korea, there are discordant voices about the real ability to miniaturize nuclear device to install it on a rocket. These doubts have been expressed precisely by South Korea, which is not considered likely that the work to miniaturize an atomic bomb actually falls in the current technical capabilities of the North Korean regime. The feeling of these statements is that Seoul circles to minimize facing a public opinion already in a state of alarm, but which is substantially, albeit within certain limits, accustomed to the situation. The South Korean government would be taking advantage of this addiction so as to avoid generating too much panic in the population. In fact, the ostentation of a calm, not at all understandable, it seems a strategy to control also possible initiatives by sectors of the armed forces under a lot of stress. In any case the will of Obama is to face, at the time, the other with a soft approach, that does not create reactions rash. And in this context, the detection capability of the North Korean official has the meaning of the world communicate its concern.
