Gush Shalom warned Israelis on Tuesday that letting Israel Beiteinu Chairman Avigdor Lieberman into the government would "raise a black flag over Israel."
The left-wing organization, whose "primary aim", according to their website, is to make "peace and conciliation with the Palestinian people" through "accepting [their] right...to establish an independent and sovereign State of Palestine in all the territories occupied by Israel in 1967," called Lieberman "a threat to the fabric of Israeli society" in a letter published in Ha'aretz.
Gush Shalom compared Lieberman to "racist Joerg Haider" whose presence in the Austrian government caused Israel to recall the country's ambassador to Vienna.
"The very idea that such a person, which such views, can be a member of the Government of Israel is shocking. It shames everyone who advocates it," the organization wrote.
