There are many Arabs who cooperate with Israel because even they know what a horror show the PLO/PA is, but the Israelis who cooperate with Arabs against Israel are liberal scum.
I had two Arabs cleaning my house yesterday. Nice fellows. No idea what they really think about the PLO/PA, but they did a good job cleaning, and we paid them a bit extra, and I had to escort them to the yishuv’s exit and vouch for them so that they could leave. They told a car-full of Arabs entering the yishuv to give me a lift back towards my house. Since they were inside the gate and heading in, I took the ride. No way I would do that to get to tzomet hagush, though.
