Go live as a civilian in a country that our military has decimated with bombs and then say again that "military bad" is just a vibe.
As for their aims, you can believe it’s about Palestine but that seems more pretextual. Historically the Houthi’s have been extremely anti Saudia Arabia and the normalization talks with Israel pose a substantial threat to them and Iranians (not to mention the US historically is allied with Saudia Arabia). It’s possible that this is just retaliation for all of that but some believe that this is their attempt to draw in the US and UK into another middle eastern war which works further weaken them which is beneficial for the Iranian/Russia/China interests to establish a new world order.
Moving a step away from facts towards analysis: the Houthis are widely considered to be an arm of the IRGC (the IRGC counts them in their "axis of resistance"). The Houthi/Saudi war seems to have been instigated in large part by Iran, whose long term conflict with Saudi Arabia is probably the most salient in MENA.
It probably doesn't make much sense to talk about what set of concessions would get the Houthis to stop; they've attacked ships indiscriminately, and have been doing so long before October 7.
The only thing I’ll note is that groups can have multiple goals. While destruction of Jews/Israel may be a rallying call and was a founding principle, Houthis can want other things and do have other enemies (Saudia Arabia is disliked by Houthis independently of Iran’s conflict with them).
When all those leaders gather in one place how can our angry pitbull not froth at the mouth? Not saying it’s ethical, just that it’s purely rational.
