The Joint Comprehensive Plan of Action, agreed in 2015, required Iran to limit uranium enrichment to 3.65% purity, reduce its stockpile by 98%, and allow international inspections in exchange for sanctions relief.
Iran largely complied until 2018, when the US withdrew and reimposed sanctions, prompting Iran to resume enrichment beyond agreed limits.
As of 2026, Iran maintains influence score of 41/100 in regional dynamics, with 77 tracked signals concentrated on Iranian activities. Negotiations for deal restoration have stalled, and Iran continues advancing its nuclear program beyond JCPOA constraints.
Geopolitical tensions extend beyond nuclear issues. Recent incidents include arrests related to alleged plots targeting communities and security incidents like the RAF Fairford case involving UK Iranian dual nationals. Simultaneously, fighting intensifies in Yemen with hundreds of casualties, reflecting broader regional instability that complicates any potential nuclear agreement revival.
