>>509852201because every country in the world has been on a massive demilitarization binge since WWII and or the fall of the soviet union so now they have enough trained men and equipment to defend their own territory for a year at best and if they start using their military to keep shipping routes safe they will run out of money and missiles and maybe lose some of the ships that they can't easily replace. the only exceptions to the above are russia, china, and the US. Russia is currently dumping resources into ukraine which is having all the excess resources of nato dumped into it to counter the russians. It's bleeding nato dry because there isn't much left of the european military industrial complex. The US went all in on diversity and equality and shit so our military is thirty to fifty year old tech that is still bleeding edge but it's being piloted by unqualified idiots and the same thing can be said for our military industrial complex. China is the only country actively arming and improving its defensive capability. It still isn't as good as the US though and does not have force projection. It is also in china's interest to let all of these western owned ships get shot up by the houthis, it increases china's shipping marketshare.
tl;dr: the US is the only country that could do anything about this but our military and military industrial complex are full of incompetent diversity hires so we can't
