The re-imposition of specific sanctions against Iran's military for its ballistic missile program made this move problematic since the Revolutionary Guards control an estimated 78% of Iran's economy through a myriad of shell companies, including the Ministry of Telecommunications governing all phones and internet access. The IRGC uses the profits to fund its proxy wars in Yemen and Syria, as well as supply cash to terrorist groups such as Hezbollah. It's important to remember that the vast majority of the Iranian economy is state-controlled so this move was unavoidable. Hopefully it begins the process of applying the kind of pressure that led to the nuclear negotiations in the first place, but this time we shouldn't appease the regime and this time tie improvements in human rights, women's rights and freedom of the press to a new deal. Ultimately that would be a greater service to the Iranian people.
