Dropping bombs is an act of war, so yes. I guess the de jure, internationally recognized state of Yemen approves of the bombings, but the de facto state run by the Houthis is at war with the US.
Of course, the Houthis have committed acts of war first by violating the rights of the sea, so take that as you will.
Iran is a whole ass country, the Houthis are a rebel faction, for lack of a better term. I think this whole situation is kinda different... Matter of opinion I guess...
Houthis are the de facto government of Yemen which is important because the US is claiming the right to self defence which is only available between states.under international law. That's why for example Israel's argument of self defence is nonsense because Gaza is not a separate country.
They're a rebel faction that controls most of the country, including the capital. It's different, but they're a lot closer to a government than something like Hezbollah.
Sure. But these are not the same actions. Defending shipping interests has been a legitimate cause for military force ever since humanity invented shipping.
"There is no difference between an attempt to start a war with an organized state of millions of people which has engaged in no provocation beyond international norms, and a strike against a terrorist group currently attacking civilian shipping." - Most Informed "BOTH SIDES" Fan
