US maximum pressure campaign on Iran (2018-2019)
The US withdrew from the Iran nuclear deal in May 2018 and reimposed sanctions, pressuring countries to cut Iranian oil imports. Several countries, including Iraq, received waivers but faced pressure to reduce trade with Tehran.
Iranian oil exports dropped sharply, and Iran's economy contracted.
Iran continued trading through neighboring countries and informal channels. The campaign did not force regime change.
Shows how US sanctions pressure on Iran affects neighboring countries' trade decisions, similar to the current pressure on Iraq.
