Anyways, if you want to do actual direct action to stop something like this happening. Whether again to the Palestinian people or to another group in the global south then you have to start joining local labour movements where they exist. Local socialist groups where they exist. You can not wait for the genocide to begin to start thinking about these things. Most people on this website I believe are under the age of 25, probably averaging around 23, so this really should be your awakening moment to get up and do something within the local community and connect with the radical movements of other local communities around you. If you create these networks now, build up the forces necessary to bring the economy to a screeching halt then this will not happen again. It will truly be never again.
But we can not wait for ethnic cleansing to start. We owe it to every victim of genocide from Namibians in 1910 to Palestinians today to stop another event like this and all others from happening.
What you can do for Palestinians right now at this moment in time is mass communication, protests, boycotts and withhold your vote from those who have enabled this when the time comes to vote and most importantly, keep the momentum going. Do not fall to despair. When a ceasefire is reached, do not falter, do not let this sink into the back of your mind. Keep putting pressure on corporations, on local politicians and representatives and use this momentum to do something about the system we're all suffering under to greater and lesser extents.
