I say enough with the sanctions as they usually only cause collateral damage among a nation's citizenry and provide the regime an excuse as to why their citizen's lives aren't up to par. If one goes to the State Departments website, they will find that travel to Iran is rated as a Level 4 - Do Not Travel. It then reads as follows: "Do not travel to Iran due to the risk of arbitrary arrest and detention of U.S. citizens.
There is a very high risk of arrest and detention of U.S. citizens in Iran, particularly U.S.-Iranian dual nationals.
Iranian authorities continue to unjustly detain and imprison U.S. citizens, including students, journalists, business travelers, and academics, on charges including espionage and posing a threat to national security. U.S.-Iranian dual nationals are particularly susceptible to arrest for these charges. Consular access to detained U.S. citizens is often denied.
The U.S. government does not have diplomatic or consular relations with Iran. The U.S. government is unable to provide emergency services to U.S. citizens in Iran. Switzerland serves as the protecting power for U.S. citizens in Iran, providing limited emergency services. The Iranian government routinely delays or denies Swiss officials access to detained U.S. citizens."
