Iran and North Korea are simultaneously and significantly escalating their nuclear threat programs. Their action portends two rising national security crises as the 2020 campaign heats up.

Iran’s action this week centers on its reactivation of uranium enrichment centrifuges at the Fordow nuclear facility. Buried inside a mountain, the facility poses a special threat in its reduced visibility to intelligence efforts and hardened position against prospective military strikes. Fordow’s reactivation follows other Iranian nuclear threats this summer.
