Exterminate all terrorists and their supporters. Last year, Israel had an opportunity to take out a bunch of terrorists but they used a smaller bomb than they should have because they were worried that "innocent" Arabs might be killed. The terrorists weren't killed. In another incident, the Israelis use ground troops, exposing them to greater danger (and some of them were killed), to avoid killing "innocent" Arabs. The Arab culture is one of hatred and death. They glorify it and teach it to their children. While there are some Arabs who are truly innocent, the overwhelming majority allow the culture to go on. If the Israelis continue to care more about innocent Arabs than innocent Jews, they will be destroyed.
Do you think the world community would tolerate large scale slaughter of Arabs even if the main target was legitimate? How long before Israel would face sanctions or even foreign intervention? Also the assumption that "most" Arabs are out to kill us is one that you know I don't accept. We've had that discussion.
This is the problem I have with the far right "solutions" to massively kill or transfer the Palestinians. I feel the consequences to Israel will be far greater than anything the Palestinians or even the Arabs as a whole can inflict upon us.
