The sanctions have worked with North Korea but not Iran

According to the UN, international pressure, the economic blockade and international sanctions have caused the withdrawal to persist in regard to the nuclear arms race of North Korea. The issue has held sway for some time, almost suddenly deflating in a sudden, after that the whole world had feared the nuclear accident, repeatedly threatened by Pyongyang. Despite the alarms caused, several South Korean experts had always warned that the North Korean regime would not have gone beyond the serious threats professed, but many analysts feared equally header of the regime tried by a very serious economic situation and the threats made specifically against the United States, which have become possible target of missiles with nuclear warheads. However, if the escalation seems to have stopped, the progress made by Pyongyang's nuclear tests confirm the advanced stage reached by the North Korean nuclear technology, thanks to the use of plutonium, which allows for greater miniaturization of devices and therefore greater ease of transport of the missiles. The current truce, certainly due also to the reasons identified by the UN, does not seem, however, be exclusively the result of the statement by the United Nations is not, in fact, conceivable that a silent pressure of China, has not, at least, contributed to stop the development of a situation that seemed to be directed on a track dangerous. Moreover, only Beijing could still exercise an influence that can have positive effects on the so-called state hermit. The situation in North Korea, however, is not comparable to that of Iran, where threats have not had the similar effect, it must be said, however, that Pyongyang has atomic weapons and Tehran seems to be still far away, but the fact remains that the conditions imposed to North Korea by the UN had no effect for self-isolation that was imposed Pyongyang, you can not enjoy the network of relationships woven from Iran, through the religious element and the large investments made to countries in the developing in Islamic. The two situations are not comparable and the North Korean diplomatic success achieved over the country does not seem to have the conditions to be repeated in the Iranian one. This may constitute an additional element to the theoretical pre-emptive strike on Iran, strongly supported by the Israeli government in charge and that seems to have opened a breach in the executive also of Washington, who took note of the failure of the sanctions policy with the country of Iran.
