Naphtali Bennett is one of the hard-right figures in Israeli domestic politics, according to Iran International. His appointment as defense minister could also influence the future of the Israeli government.
Bani Gantz, the leader of the Blue-White coalition, is currently in charge of government formation by Israeli President Reuven Rivlin.
If the leadership of the blue-white coalition, like Netanyahu, the leader of the Likud party, fails to form the remaining government, Israel must hold a general election in less than a year.
Netanyahu had earlier said in retirement during his remaining term, "In the past few weeks, I have made every effort to bring Benny Gantz to the negotiating table. "I made every effort to create a comprehensive national government and prevent another election."
The closeness of the new right wing to the Likud party, led by Netanyahu, could strengthen the position of the current prime minister. However, efforts are underway to form new coalitions on the opposite side.
The Knesset, the Israeli parliament, has two seats and will inevitably be a "coalition" with the votes of the next Israeli government.
Gantz is a retired Army general. In the two previous elections, he ran as the leader of the newly formed Blue White coalition, Netanyahu's main rival, and achieved very good results. The Likud Party won two seats in the September 26 general election and the Blue White party won two seats.
On Thursday, it was announced that Israel's Bethna Party, led by Avigdor Lieberman, largely backed by secular rightists, had reached a preliminary agreement with the blue-white coalition. It opposes the influence of traditional and religious forces in Israeli politics.
Since Lieberman's resignation as Israel's former defense minister, Netanyahu has served as secretary of defense.
