Undoing the 'tangled nest' of Iran sanctions won't be easy or quick

The U.S. has granted Iran a temporary reprieve from sanctions, potentially unlocking billions for Tehran. However, dismantling over four decades of stringent sanctions involves intricate legal, political, and commercial hurdles that could extend over years. This move is significant as it impacts international relations, particularly in the Middle East, and could reshape global energy markets, given Iran's role in oil production. The complexity underscores the delicate balance required in re-engaging with Iran and the broader implications for global diplomacy.
