Saying a deal is in crisis mode means negotiations have stalled, violations are happening, or politics have shifted. In U.S.-Iran relations, this usually points to the 2015 nuclear deal, the Joint Comprehensive Plan of Action. The JCPOA entered crisis after the U.S. pulled out in 2018 and reimposed sanctions. Iran responded by enriching uranium past agreed limits. Talks to revive the agreement under the Biden administration failed. Recent Iranian centrifuge activity and U.S. diplomatic inaction have deepened the tension. The phrase signals severe instability in the JCPOA driven by stalled talks and mutual escalation.
