Biggest issue is that this isn't like in 2010 when Somali pirates were attacking any target of opportunity. The houthis have played it smart by researching the background of ships passing through that area and only interdicting ones affiliated with Israel. For most nations, this isn't their problem because their commerical ships have been unmolested. Hard to get a wide ranging international coalition put together when it really isn't an international problem.

It's firms from mainly the US, UK, and Netherlands that all refused to cancel freight to and from Israel, which is why they are crying to their governments for military protection. The big cargo carriers based out of Asia all responded by canceling freight to and from Israel, which isn't a real problem for them because they make thousands of times more revenue from freight between Asia, Africa, and Europe. For example, the Chinese naval strike group in the area has been just chilling because the houthis have ignored Chinese owned shipping.
