In January 2017, the United States will welcome a new President who is likely to face the critical issue of a nuclear-armed Iran. The actions taken by President Obama regarding the Iran deal will significantly affect the international stance on sanctions. If the deal has weakened the consensus around these strict sanctions, reinstating them could be extremely difficult and time-consuming, possibly giving Iran enough time to develop nuclear capabilities.

This impending scenario underlines the urgency and consequences of diplomatic decisions related to Iran. According to Ted Cruz's book, the potential inability to re-establish sanctions after they have been relaxed could leave the U.S. and its allies with limited options to contain Iran's nuclear ambitions, creating a serious threat to global security.
