One who betrays one's country, a cause, or a trust, especially one who commits treason (the free dictionary)Israel is a country under all sorts of attacks in a war for survival. Many countries unabashedly state they want us destroyed. So, you'd think, hope that the state of Israel would be more vigilant about traitors and sedition.
Every once in awhile a politician looking for headlines will initiate something like this:
Coalition head aims to remove B’Tselem head's citizenship
B'Tselem director Hagai El-Ad speaks to the UN Security Council on October 14, 2016 (YouTube screenshot) Times of Israel
"Elad's actions at the Security Council are a blatant violation of the trust citizens must have for their state, so he should go find another country where he could be a citizen."
But nothing much ever happens, certainly nothing that could stop these acts. It doesn't pay to try them here in Israel, because the courts are Leftist, too..
