WASHINGTON ¨C Tehran stands to gain billions of dollars from a 60-day reprieve from U.S. sanctions announced on Monday, but unwinding more than four decades of restrictions poses legal, political and commercial challenges that could take years.
At issue is whether an interim U.S. deal with Iran can translate into lasting economic relief, given the complexity of dismantling a sanctions regime that spans U.S. law, international measures and private-sector risk concerns.
The United Nations, the U.S. and the European Union have imposed sanctions and trade embargoes and have frozen assets since the late 1970s over Iran¡¯s nuclear program, human rights violations and support for militant groups around the region.
