State Dept.:

The end of the Cold War forced new thinking among policymakers and analysts about the greatest challenges to U.S. national security. The emergence of al Qaeda, cybercriminals, and other dangerous entities affirmed the threat of nonstate actors. But equally daunting has been the resurgence of outlaw regimes—rogue states that defy international norms, fail to respect human rights and fundamental freedoms, and act against the security of the American people, U.S. allies and partners, and the rest of the world.

Chief among these outlaw regimes are North Korea and Iran. Their transgressions against international peace are many, but both nations are most notorious for having spent decades pursuing nuclear weapons programs in violation of international prohibitions. Despite Washington’s best efforts at diplomacy, Pyongyang hoodwinked U.S. policymakers with a string of broken arms control agreements going back to the George H. W. Bush administration. North Korea’s nuclear weapons and ballistic missile programs continued apace, to the point where after Donald Trump was elected, President Barack Obama told him that this would be his greatest national security challenge. With Iran, likewise, the deal that the Obama administration struck in 2015—the Joint Comprehensive Plan of Action, or JCPOA—failed to end the country’s nuclear ambitions. In fact, because Iran knew that the Obama administration would prioritize preserving the deal over everything else, the JCPOA created a sense of impunity on the part of the regime, allowing it to increase its support for malign activity. The deal has also given Tehran piles of money, which the supreme leader has used to sponsor all types of terrorism throughout the Middle East (with few consequences in response) and which have boosted the economic fortunes of a regime that remains bent on exporting its revolution abroad and imposing it at home.
