Professor Murrett’s Comments

“Today鈥檚 announcement today that the U.S. will commence ‘blockading any and all ships’ trying to enter or leave the Strait of Hormuz (SoH) represents a military option with certain advantages, and moreover, possible international support:

  • First, full and unconstrained access to the SoH is in the interests of all nations (including Iran), and one that is vital to global economic interests. None of the nations adjacent to the SoH (Iran, Oman and the UAE) should hamper this freedom of navigation, as they have not in the past.
  • Nearly all nations have an interest in free access into and out of the Persian/Arabian Gulf, and there is potential for conducting this operation as a combined naval effort with participation from several allied nations, which is preferable. The goal would be to have free and open access for all nations, or none.
  • Geography matters: The blockade can also be enforced in areas that are not as advantageous for Iran a others, that is, in the Gulf of Oman rather that in the SoH narrows adjacent to Larak/Qeshm Islands.

These are just some initial thoughts, as the operational dimensions, participants, implementation and tactics evolve in the hours and days ahead.”

Will the Blockade Work?

鈥淭he blockade 鈥榗an work鈥 from my estimation from the standpoint of the naval forces’ ability to stop traffic in and out of the Gulf,” Murrett says. “On the other hand, it is an open question as to whether or not will this military operation will 鈥榳ork鈥 as a means to compel the Iranian leadership to re-open the SoH for free access, as was the case before the current fighting started. The second question is the more important one.鈥
