Lieberman is a Soviet-born Israeli politician who served as the Defense Minister of Israel; on November 14, 2018, Lieberman announced he was handing in his resignation due to a ceasefire versus Gaza, which Lieberman said was "surrendering to terror".
He served as Israel's Minister of Foreign Affairs from 2009 to 2012, and again from 2013 to 2015. He has also served as member of the Knesset and as Deputy Prime Minister of Israel.
He is the founder and leader of the secular-nationalist Yisrael Beiteinu party, whose electoral base consists of overwhelmingly Russian-speaking immigrants from the former Soviet Union. As a result of the arrival in Israel during the 1990s of more than one million Russian-speaking immigrants, Yisrael Beiteinu has regularly played the "king-maker" role in Israel's coalition governments.
