NUCLEAR WEAPONS

South Korea is on high alert following a supposed hydrogen bomb test from North Korea.

Preventing trade with the country has hurt its economy, but the real victims are civilians — making it hard for the world to gain leverage.

While the test would be North Korea’s fourth test in ten years if the news is accurate, the history of the North’s nuclear weapons program can be traced back to the country’s founder, Kim Il Sung.

But the United States has a long and strained history with North Korea; it's not just the current administration.

The International Atomic Energy Agency called a potential hydrogen bomb test a clear violation of U.N. Security Council resolutions and “deeply regrettable."

North Korea said Wednesday that it tested a hydrogen bomb to assert its right to “self defense” against the U.S. and other enemies.

A hydrogen bomb, which is powered by nuclear fusion, is much more destructive than an atomic bomb.

Pyongyang tested a submarine-launched ballistic missile in December, following the failure of one in November, according to a report.

U.S. Secretary of State John Kerry called the shipment “significant” in the fulfillment of a landmark nuclear deal between Tehran and six world powers.

Tehran responded to the International Atomic Energy Agency’s report Wednesday saying that it considered the U.N. investigation closed.

During the process, the Arak heavy-water reactor will be reconfigured so it cannot yield fissile plutonium usable in a nuclear bomb.

Reunions, which North Korea uses for leverage, resume after a confrontation in August.

The U.S. military was supposed to place new weapons in Germany by yearend, but officials said the transfer would likely take place closer to 2020.

The U.S. Air Force was slated to station new nuclear weapons in Germany by 2015, but that move will be delayed until 2020.

The United States is planning on stationing more nuclear weapons in Germany, according to a German TV report.

Contradicting reports have surrounded the probe over whether IAEA chief Yukiya Amano Yukiya Amano was present during the collection of samples.

The experts said the failure to disclose the details was damaging the credibility of the International Atomic Energy Agency.

While India is a far wealthier country with greater resources, international estimates suggest that Pakistan has around 120 warheads, while India has 100.

South Korea announced that its military would not need to seek approval from leadership before firing back at its northern neighbors.

On the 70th anniversary of the historic nuclear attack, Japanese peace activists called on their government to dial back its proposed military expansion.

While the uranium could not have caused a nuclear explosion, it could be altered through a scientific process and then used inside a dirty bomb.
