There was/is a case to be made because of the shipping routes. However I think arming crews or escorting is a better solution.
The whole reason we originally intervened was because we were stampeded into putting boots on the ground there by the MSM constantly showing starving distressed Somalis (children mostly!) on TV! The soccer Moms of America couldn’t stand it! Also there was this constant drumbeat (again aided and abetted by the MSM) by the Congressional Black Congress that the reason we weren’t helping was because we are racist! This was particularly true in the waning years of the Bush I presidency. He probably had a ton of Beltway GOP PR guys telling him that the GOP would lose seats in the House & Senate if he didn’t intervene. Then through the financial incentives that the USG provided NGOs during the Clinton, Bush II & Zero years. ( I am sure Bush II had the same GOP PR wankers telling him something similar!). Zero of course accelerated it. Too me the real villains of all this are the NGOs who make a fortune off bringing Somalis (Khat addicted primitives!) here (Now Central Americans!). USG pays and they drop them off in the USA and take no responsibility for their care, welfare or behavior! Particularly their behavior, these NGOs many church affiliated need to be held civilly & criminally responsible for the behavior of those they bring in. They are nothing more then human traffickers and should be treated as such!
Only one problem with your theory, the troops went in Dec. 1992, after the election.
