Okay. And why should we care?
Seriously, outside of this being a great reason why relying on overseas trade is a bad idea and that we need to bring industry back to America, I fail to see why the USA should involve ourselves in more overseas squabbling.
In fact I more then have suspect the reason why the US’s political establishment is so determined to undermine US industry is that it gives them an excuse to get involved and get money from the military-industrial complex and so on by ensuring the USA feels it needs to get involved overseas and keep up its global empire.
Because AShMs with the range to close off the Red Sea and threaten the Suez Canal to commercial traffic affect everyone, even us.
The world's economy is dependent on unfettered access to both the Panama Canal and the Suez Canal. Close off or threaten even one with long term closure, and the cost of everything goes up if ships are forces to go around the tips of Africa and South America again.
Even the Pharoahs built their own system of canals to connect the Med and Red Sea, because they knew how vital that link is.
The Houthi's have already shown they will fire IRBMs into Saudi Arabia and launch anti-shipping missiles at US and allied ships years ago. They've stuck limpet mines on tankers and cargo ships throughout the region, and did you forget that time Iran grabbed a bunch of US service members in the Gulf and forced us to do a prisoner swap for them.
If the Houthi's control all of Yemen, they can launch IRBMs at the Suez Canal and Egypt pretty easily, along with effectively closing off the Red Sea to all non-Iranian friendly sea traffic. As well, they could then launch even more attacks into Saudi Arabia if they had complete control of Yemen, and be a threat to a lot of maritime traffic in the Eastern Indian ocean as well. Turns out a lot of our Asian allies have vital trade links in the region, and it is no less vital to many of our European allies.
It's like some people here have forgotten how much our modern world and modern economies is predicated on the Suez Canal existing in an open and unimpeded state, and how much the gear the Houthi's have can threaten that.
The US pulling out of the war in Yemen will not do anything but make it easier for the Houthi's and Iran to threaten even more people and international trade.
