UN General Assembly set to hold emergency meeting on Gaza after Egypt and Mauritania invoke UN Resolution 377

Resolution 377 allows the UN body to take action whenever there was an indication that the UN Security Council may have failed to “exercise its primary responsibility for the maintenance of international peace and security”.

United Nations General Assembly (UNGA) resolution 377 A, the "Uniting for Peace" resolution, states that in any cases where the Security Council, because of a lack of unanimity among its five permanent members (P5), fails to act as required to maintain international security and peace, the General Assembly shall consider the matter immediately and may issue appropriate recommendations to UN members for collective measures, including the use of armed force when necessary, in order to maintain or restore international security and peace. It was adopted 3 November 1950, after fourteen days of Assembly discussions, by a vote of 52 to 5, with 2 abstentions. The resolution was designed to provide the UN with an alternative avenue for action when at least one P5 member uses its veto to obstruct the Security Council from carrying out its functions mandated by the UN Charter.

Emphasis added. I read the definition in the article but I didn’t see it didn’t specify the powers that gives the GA.

Fact that Mauritania is the cosigner makes me think Egypt just wanted anyone at all to go along with them so they can basically threaten Israel under UN sanction

I'd be shocked if it worked, mostly because escalation at this point is immediately going to ignite like 50 different proxy, civil, and interstate wars as KSA and Iran throw all the shit straight into the fan playing then counterplaying each other and taking their attention off secondary conflicts until we somethefuckhow wind up with the war for greater Azerbaijan becoming a thing because Netenyahu thought starting an irredentist genocide was how he'd save himself from being dragged into the streets like a Likkud Ghadaffi over trying to rig the courts in retaliation for them pointing out that the current plans for Irredentist genocide were illegal even under Israeli law.

What will they do to stop the US from vetoing once again?

Is there a course of action that's going to be proposed? I don't expect that anyone will want to get involved in the fighting directly, but if that's not on the table then what influence does the UN have here without US support?
