If the Navy feels understaffed and overworked, they can stop illegally blockading countries.
Also, which countries is US actively blockading illegally?
Quoting from that link, "The United States had joined the blockade in October 2016" and "According to the international law of naval blockade the naval measures conducted by the coalition led by Saudi Arabia do not amount to a naval blockade in the legal sense" and "Due to the devastating famine in Yemen and supply shortage of essetinal goods, which are caused by the enforcement measures, the naval operations off the coast of Yemen are criticized as a violation of international humanitarian law."
They are supposed to require a deceleration of war going through Congress, but that has largely been circumvented. They are not just some puppet, the ballooning budget shows their input is considered. If there were some sense that the Navy was resisting the current state of affairs, I'd be more sympathetic.
And the other poster is correct, I was considering the Yemen blockade. Any pretense of legality requires deliberately bending the description of what's taking place, or acknowledging that the US has made itself exempt from prosecution for war crimes.
