Former Israeli military Chief of Staff Benny Gantz, considered Prime Minister Benjamin Netanyahu's top rival in the upcoming Israel election, published four videos on Sunday under the headline "Only the strong wins."

In the short videos, published on his Hosen L'Yisrael party's YouTube channel, Gantz takes pride in the assassination of Hamas military chief Ahmed Jabari, bombing 6,231 targets in the Gaza Strip and killing 1,364 terrorists, The data is written on the screen against the backdrop of images showing the destruction of Gaza and accompanied by dramatic music.

Gantz's new party launched its campaign Thursday and is running under the "Israel Before Everything" slogan.

According to two new polls released Wednesday, Gantz's party would receive 13 seats in the 120-seat Knesset if elections were held now. The polls also showed that 31 percent of Israelis believe Gantz is more suitable than Netanyahu for the prime minister post, compared with 42 percent who favor Netanyahu.

Over the past several days, lawmakers from Netanyahu's Likud party criticized him over the death of an Israeli Druze border policeman, Madhat Yusuf, during the second intifada. Yusuf was shot and bled to death at Joseph’s Tomb near the West Bank town of Nablus in 2000 when Gantz was the commander of the army’s West Bank division.

The statements came after Gantz criticized the controversial nation-state law in the face of Druze community protests about the law.
