Support the prevention of nuclear weapons by the North Corea

Considering the usage and existence of nuclear weapons as a threat for the whole humanity, we strongly encourage Obama Administration to take serious actions to prevent preparation of nuclear weapons in the North Korea. Even the UN Security Council has adopted five major resolutions that impose and strengthen sanctions on North Korea for continuing to develop its nuclear weapons program. Somehow, more actions must be taken so that the North Korea refrains from ballistic missile tests.
To this date, UN Security Council resolutions have failed in preventing North Korea from resuming its nuclear weapons and other dangerous missile programs. In spite the fact that, the sanctions have slowed development in these areas, human lives are still in threatening situation.
