Won't alienating all your allies lead to increased US spending in the end?
Keeping it cheaper.
When the Suez was blocked by a sideways ship[0], some of shipping went around Africa[1].
The USA also notably made it clear to the European powers that European powers absolutely didn't have any right to be the powers who controlled the Suez[2].
I also note that the official position of the Houthis is their attacks on shipping are supposed to be about Israel, the problem from the perspective of everyone else in Europe is that they're idiots hitting unrelated ships as well[3].
