To say “welp we tried, screw negotiations forever and ever” is shortsighted. Israel was never negotiating for an independent Palestine, even during the high points of Oslo or Camp David. It always wanted a subservient Palestinian Authority, with no actual control over security or borders, and no right of return for Palestinians - a deeply hypocritical stance whilst Israel rubber stamps Jewish immigration and citizenship, and funding Aliyah trips for international Jews with no ties to Israel
Israel today isn’t offering any solution but continued suffering, displacement as refugees, or ethnic cleansing. I disagree with the Palestinian resistance’s methods, but we are here because of years of failed peace processes where Israel rejects the option of dignity for Palestine.
You need to show the civilians living in the area that there’s another way via political process, and that rejecting violence is the way forward. Al-Qassam exists and is given permissive operations inside of Gaza because the people view them as the best route to a future. Throwing stones at a brick wall isn’t effective, but to Palestinians in a hopeless scenario it’s understandable to take up violence when the alternative is ethnic destruction in slow-motion.
