Many of the arab citizens who demonstrated live on social security benefits that come from the taxes you pay.
These people are not stupid. And if they are, their leaders are not. They depend completely on israel and they know it. There are no UNRWA agencies in Umm-Al-Fahm, nor money from donor countries. They cannot carry on a long war.
Israeli arabs are protesting against their discrimination and mix nationalistic propaganda into the struggle, but I suspect this propaganda will soon be dropped. We will see what happens in the coming days.
