Anthony Blinken, admitted that the FTO designation has only resulted in a travel ban for ordinary people. He states "As a practical matter, the designation does not gain you much because there are myriad other sanctions on the IRGC. The primary sanction when it comes to the FTO designation is a travel ban. And the people affected by that ban when it comes to the IRGC, as you know, the IRGC is a large force that has a lot of conscripts in it. They would not be able to travel. The people who are the real bad guys have no intention of travelling here anyway" (link)
