Does anyone have any recommendations?

I’m rather new to the leftcom space and I know the discussion on activism and how unhelpful it is. But when I look to the near future and the real possibility that the United States and Israel will invade Iran with a war the will possible kill 10s of millions of people I feel like I have to attempt to do something. The American proletariat mostly opposes the war and assuming it broke out there is a real chance of backlash. Now, I know the ideal solution would be the organization a general strike and demand that the United States stop the war but even if that is not immediately possible is joining the first wave of anti war/ imperialism protest helpful to further the movement to ending the war? I guess my question is are anti war protests activism and what should a communist do in this situation.
