Wrong. First Yemen IS signatory since 1987 (or 1989 if you consider North Yemen). Second, the convention gives responsibilities beyond borders for members, and explicitly puts responsibility to act upon signatory States. And third, there are plenty previous cases that opened precedence that a country can act even before any approval from UN (US bombed Yugoslavia arguing this), and there is also precedence of blockades enforced by a single country despite the lack of approval (and despite disavowal) from UN (US blocking Cuba and Venezuela).

> I think it is perfectly valid for a country to protect its own citizen from being burned alive among many other atrocities that were committed, which is also one of the reasons the genocide convention was created in the first place.

Also wrong. The genocide convention was created to prevent genocide. There is nothing in the convention mentioning that you should not act if the victims are from other countries. On the contrary, the convention says that you must act to prevent and has an extraterritorial scope (as was established in a previous judgement in UN).

How exactly killing children, reporters, women and people holding white flags, attacking UN shelters, as well as destroying hospitals and universities prevent more October 7 attacks!? In fact, it will create more attacks because of the anger from an oppressed people. Which was the cause of October 7 attacks, by the way. Sorry, declaring war is not a free pass to commit war crimes. If the war crimes are frequent, and they are not opposed (or if they are encouraged), this is a serious evidence of genocide.
