US Congress may give Iran deal greater legitimacy
Significance The White House had opposed the bill, and launched one of the most energetic lobbying campaigns on Congress of Barack Obama's presidency. After the bill's passage through the committee, both Republicans and Democrats argued that the legislation favoured their agendas, which had been largely mutually exclusive. Impacts The Corker bill creates some credibility problems for the United States on long-term sanctions relief. With US sanctions more likely to be lifted, other nations may follow Russia in lifting unilateral sanctions. Iran will nonetheless become a major issue in the Republican campaign for the presidential nomination. This could lead to a subsequent Republican administration seeking to reimpose sanctions on Iran for different reasons. The deal will not affect US-Iranian tacit cooperation in Iraq and hostility in Syria and Yemen.
