Not allowing a foreign seafarer who does business with our enemies to obtain a visa or bank account does not come close to Houthi’s sinking merchant ships or killing crew. That’s a total false equivalency.
If FOC officers are so beholden to shipowners that they can’t turn-down/quit a job that risks the ire of United States foreign policy, that’s on them(all three of them in this case?) They’ve made their decision and these are the consequences. I suppose the same could be said of Americans transiting the Red Sea risking themselves against Houthi “foreign policy”, but I know which side I prefer.
