The Al-Monitor article linked to below presents compelling evidence that the Obama administration is subtly undermining the highly-touted nuclear deal reached last year between Iran and the consortium of the US, the EU, Russia, and China.
The continuing efforts of the Treasury department to sanction Iran, despite the commitments made in the Iran deal, is consistent with previous American rebuffs to Iranian peace overtures made by the liberal predecessors of the current President, Hassan Rouhani.
As the article notes: "In the 1990s, then-President Ali Akbar Hashemi Rafsanjani’s outreach to US oil firms was met with Congress’ passage of the Iran and Libya Sanctions Act, the foundation for subsequent secondary US sanctions targeting the Iranian energy sector. In the early 2000s, under then-President Mohammad Khatami, tacit Iranian-American collaboration to successfully overthrow the Taliban ended as the Islamic Republic was labeled a member of the infamous Axis of Evil.”
