Iran fast-boat swarms add to Hormuz threats for shipping

They have been building this capability for decades. The lack of countermeasures by the US military shows the complete lack of planning by the Trump administration. Ukrainian forces would be better prepared to deal with this, but Trump says "they have no cards". This is why you build alliances, not destroy them.

"Trump: Boats had not been considered much of a threat." Relied on the overall power of the US military without a detailed strategy and overestimated the fear factor.

See: Millenium Challenge 2002. We had all the expectation this would happen over 2 decades ago. "Thus warned of Blue's approach, Red used a fleet of small boats to determine the position of Blue's fleet by the second day of the exercise. In a preemptive strike, Red launched a massive salvo of cruise missiles that overwhelmed the Blue forces' electronic sensors and destroyed sixteen warships: one aircraft carrier, ten cruisers and five of Blue's six amphibious ships. An equivalent success in a real conflict would have resulted in the deaths of over 20,000 service personnel. Soon after the cruise missile offensive, another significant portion of Blue's navy was "sunk" by an armada of small Red boats, which carried out both conventional and suicide attacks that capitalized on Blue's inability to detect them as well as expected."

Trump said all the water boats were destroyed.

These don't really matter,  missile and drone attacks are still the main threat and leverage against shipping in the strait.  notice how these only come out during the ceasefire, they would fair just about aswell as those fishing boats have been in the carribean if the war goes hot again.

Why isn't the USA blowing up those boats like they blew up the drug smuggling boats and submarines?

That would be a fuckin awesome feeling knowing youre beating the US navy and all its might, resources etc. the salt spray, the speed, the uppers - these sailors must be the "gods of Hormuz"
