Nuclear weapons

The New START treaty expires in 2021, and the Trump administration is yet to announce whether it intends to renew.

U.N. sanctions may ultimately be reimposed on the nation.

Exclusive: Now that the U.S. has deployed a new nuclear weapon, the options presented to President Trump to respond to Tehran will automatically include a nuclear option.

Joe Scarborough's remarks came after Kim Jong Un asserted this week that North Korea "will never" denuclearize.

President Donald Trump said he thinks North Korea's Kim Jong Un is a "man of his word" after the despot warned the world that Pyongyang will soon have a "new strategic weapon."

The Russian Avangard hypersonic missile system can reportedly travel at 20 times the speed of sound.

Bolton, whom Trump ousted from the position in September, wrote in a tweet that more "effective" policy would be needed to keep the United States and its allies safe from North Korea.

North Korea has set an end-of-year deadline for U.S. officials to break the deadlock in denuclearization talks, or receive a "Christmas gift."

The former national security advisor said he does not think North Korea will ever voluntarily surrender its nuclear weapons, regardless of what Kim Jong Un tells Trump.

Gorbachev, an advocate for nuclear disarmament, said, "The key to resolving security issues lies not in weapons, but in politics."

Extending the New START nuclear arms treaty is one of those rare no-brainer decisions in a world where simple solutions are an endangered species.

Both Russia and the U.S. have accused the other of violating the Cold War-era pact that banned ground-launched nuclear and conventional missiles with ranges from 310 miles to 3,417 miles.

Russian President Vladimir Putin said in 2018 that the Avangard hypersonic missile is "invulnerable to intercept."

Little of note has been achieved in the 18 months since President Donald Trump and Kim Jong Un signed a vague agreement on denuclearization in Singapore.

Students and faculty now face a choice. They can become the next generation of weapons scientists—or they can refuse to be complicit in this scheme,

The ants had fallen down a ventilation pipe and survived for years by feasting on their nestmates corpses.

The Korean Central News Agency said that Wednesday's test was of "great significance" and involved a Pukguksong-3 missile.

The test came just one day after the North announced it would resume denuclearization talks with the U.S. this weekend.

The "super-nuke" contains up to 10 separate warheads, can travel 25 times the speed of sound—or 7,600 mph. It's scheduled to be paraded through Beijing on Tuesday while most of America sleeps.

Kim Myong Gil said Friday he welcomed Trump's suggestion that a "new method" could achieve success in talks between Washington and Pyongyang.

Dan Smith of the Stockholm International Peace Research Institute suggested nuclear weapon development was continuing despite rapprochement with the U.S.

"But I cannot possess missiles with nuclear warheads? I do not accept that," Turkish President Recep Tayyip Erdogan said.

State media called the operation a training exercise that demonstrated the country's ability to position nuclear arms close to the United States, according to Reuters.

The iconic Cold War INF treaty is now dead and buried, and another key pillar of international nuclear order may soon follow suit.

Gorbachev was the Soviet leader when the agreement—limiting nuclear capable missiles in Europe—was signed in 1987.

Reports suggested the new submarine may have been designed to carry and launch ballistic missiles, which could in future be tipped with nuclear warheads.

President Donald Trump said Sunday Iran had "better be careful" with its expansion of enriched uranium production.

The new draft rules on blessing military equipment will still allow priests to sanctify "personal weapons."

This passage was called "Strangelovian" by a Federation of American Scientists expert and the report even quoted a nuclear war theorist known as an inspiration for Stanley Kubrick's 1964 black comedy.

Enriched uranium is required to produce nuclear power, but at a higher level of enrichment it can also be used to build nuclear weapons.
