Arms Proliferation and Control

Featured

The U.S.-Soviet nuclear arms race ended in détente, but nuclear development efforts and WMD proliferation in India, Pakistan, North Korea, and Iran have caused geopolitical instability since the Cold War's end. RAND has applied strategic analysis to nuclear confrontation scenarios and international deterrence efforts since its earliest work on game theory, with particular focus on the roles of both diplomacy and missile defense systems in global as well as regional security.

    The best-case scenario for future U.S.-North Korea relations is that President Trump and Kim Jong-un remain committed to diplomacy. In the worst case, both countries' frustrations could spiral out of control.

    Where Do U.S.-North Korea Relations Go in the Aftermath of the Hanoi Summit?

    If Kim Jong-un is sincere about denuclearization, it is time for him to match his words with actions. If North Korea's nuclearization continues, the U.S. government may eventually face some pressure to take military action to stop it.

    Behind the 'Surprise' Resignation of Iran's Foreign Minister

    Mohammad Javad Zarif, Iran's foreign minister, announced his resignation after a nearly six-year tenure. His resignation has sparked as much controversy as his tenure, one dominated by overtures to the West and resulting tensions at home. Although his departure will likely be felt most acutely in Europe, it may have a deeper impact in Tehran.

    Hard to Predict Outcome of Second Trump-Kim Summit

    It's difficult to predict the outcome of the second summit between Kim Jong-Un and Donald Trump. At the first, Kim offered to fully denuclearize during President Trump's first term. But he continued building nuclear weapons and ballistic missiles. If Kim keeps stalling, serious tensions could follow.

The vast majority of U.S. observers believe that the North is bluffing. Seoul and Washington should continue to strive for transparency about the future of the peninsula.
