After more than 20 months of careful negotiations, the United States and its international partners have reached a landmark nuclear deal with Iran, designed to prevent Iran from becoming a nuclear weapons-capable state. The deal has implications that extend beyond Iran’s borders and could affect the already turbulent Middle East. Some critics of the deal claim that Iran will use the influx of capital it will receive once sanctions are lifted to fund destabilizing groups such as Hezbollah and the Assad regime. Others worry that countries such as Saudi Arabia will see Iran’s successful posturing and be emboldened to begin pursing a non-peaceful nuclear program themselves.
