From my understanding, to stop the zionist entity, the US and Europe have to fall apart economically to the point that they are no longer able to materially support the entity. As a citizen of the global south, while protesting for Palestine, another possible action is to advocate for diversification away from the US regime. Within Mexico, this is starting to bear fruit and voices like mine are starting to grow stronger in the gov't and the private sector. I am pretty sure plenty of people in the global south may have reached similar conclusions or even better ones.
All I know is that efforts to stop this genocide will bear fruit. Soon all of the material supporters of the zionist entity will face demise and nothing will stop the global resistance from finally saving our dear Palestinians. I wish there was a quicker way but the US and Europe chose to defend and interfere in favor of the entity.
