All the rhetorics from Japan, the US and others fell on deaf ears and North Korea just went ahead with its missile launch, well supposedly satellite launch.
In one statement, US said, the international community should prevent the proliferation of nuclear (weapons) technology.
In effect they are saying, that it is the privilege only of some, not everyone.
Iran can't have it. Israel can. India can have it. Pakistan shouldn't. South Korea can. North Korea must not.
