I understand the need for a clear strategy. I understand the need to articulate some aspect of it to the public. But how does anyone truthfully put an end date to military operations?
Let's look at this issue. Unhindered transit of both the Red Sea and Persian Gulf for both our vessels and our trading partners is a pretty clear national interest. Regardless how much oil we drill it is not enough to fuel all the West and Japan. Hence access to Middle East production will remain critical - and long after anyone declares victory in the green revolution.
No matter what the political tea leaves, the US will continue to maintain freedom of the seas and access to key regional markets.
With respect to Yemen specifically we have a limited number of options beyond self-defense. I have listed what I think they are in ascending order of escalation and risk.
1) Attack launchers and command and control nodes.
2) Carry out major strikes against Yemen's total military capacity.
3) Blockade Iran. Seize or sink any shipping believed to be carrying military materiel to be used anywhere in the Middle East.
4) Carry out strikes against Iranian military and command control nodes. Initial focus would be the Revolutionary Guard.
5) Boots on the ground in Yemen
6) Boots on the ground in Iran
With respect to escalated strikes against Yemen's broader military capability and governing structures, I believe this would be very problematic. In spite of a years' long conflict with Yemen, Saudi Arabia has been very careful not to dramatically escalate the war. We would have little or no support and Yemen would likely revert to a failed state.
Blockade is an act of war. I frankly think it might be worth the risk. However, Iran has meaningful capacity to retaliate in a direct military conflict at sea through a huge inventory of missiles. It is extremely likely some will get through to strike US military assets. One must also assume every American in range of Iranian supported militant groups would instantly become a target. A blockade would leave free most of the US striking capability to address those threats. The likelihood of further escalation, however, would be extremely high.
Carrying out extensive strikes against Iran itself would be a dramatic action for which I defy anyone to accurately predict the eventual outcome. The potential actions which Iran could take are significant and some could represent a meaningful threat to the Homeland and/or Europe.
I have been to Yemen. Other than a high payoff raid, it is not a place we want to introduce US troops.
Iran has a population of 86 million people. We are not going to invade and march on Tehran.
So what does any administration do? I suspect we will continue to do exactly what we are doing right now. It represents the lowest risk and is fairly effective at maintaining freedom of the seas - a critical national interest. Were I the National Security Advisor, I would be asking for a plan and risk assessment to selectively blockade Iran.
What I am absolutely certain of is that neither GEN Kurilla at CENTCOM, nor the SECDEF, nor the National Security advisor can put a timeline on this mission.
I am sure we would all benefit from others' perspectives of how to resolve this.
