Disenfranchisement
Israel has banned the United Arab List and Balad from the Knesset. Banned, that is, two Arab parties which call for a two state solution and so recognise Israel’s existence - on the grounds that they don’t recognise Israel.
They have thus exiled Israeli Arabs from mainstream democratic politics. The exiled and disenfranchised tend to move to extremes, as they’re the only place to go.
You know what the available extreme is for the Palestinians. Hamas must be grateful.
