Humbly, I disagree. The U.S. Department of State has been in lock-step with Netanyahu’s wants and needs to conduct this genocide. It has vetoed a ceasefire resolution multiple times. American uniforms, American vehicles, American arms are delivered to and used by the IDF. Domestic pressure in the US will have an effect.
Restricting deliveries of such tools to conduct genocide will hamper Netanyahu’s ability to conduct the mission, which can be advocated for by people and organizations anywhere.
If we care for a rules-based order in the world, if the majority of a religion’s followers believe in the compassionate core of their religion, we can show it, even if it wouldn’t materially affect how Netanyahu conducts his genocide.
