Lieberman has stated his opposition to forming a coalition with religious parties and refused to join Benjamin Netanyahu's coalition in April 2019.
As a result of the arrival in Israel during the 1990s of about one million Russian-speaking immigrants, Yisrael Beiteinu has regularly played the "king-maker" role in Israel's coalition governments.Lieberman entered the Knesset in 1999, and has served in numerous roles in the government, including as Minister of National Infrastructure, Minister of Transportation, Minister of Strategic Affairs, Deputy Prime Minister, Foreign Affairs Minister, and Minister of Defense.
