Israel’s war cabinet, seen as a symbol of national unity in the war against Hamas, has been shaken by political rivalry between Prime Minister Benjamin Netanyahu and centrist Benny Gantz, AFP quotes analysts as saying.

A former military chief and ex-defence minister, Gantz visited Washington on Monday before heading to London on Wednesday for high-level talks in a trip which was not authorised by Netanyahu.

It served to highlight the deep divisions between the two men as international pressure mounts on Israel over the growing humanitarian crisis in the Gaza Strip, with the war entering its sixth month.

Gantz’s visit to the United States — Israel’s staunchest ally — shows that “his level of trust in Netanyahu is very low,” said Yohanan Plesner, president of the Israel Democracy Institute think tank. It demonstrates he wanted to present an alternative view to Washington, he added.

His trip to Washington has raised attention in Israel, and drew strong criticism from ministers of Netanyahu’s right-wing party Likud. “It looks like some kind of subversion,” said Transport Minister Miri Regev, adding Gantz is “working behind the prime minister’s back.”

Dudi Amsalem, Israel’s regional cooperation minister and Netanyahu ally, said that Gantz had joined the wartime government “to create unity in an emergency, not to be a Trojan horse”. Five members make up the war cabinet, with Netanyahu, Gantz and Defence Minister Yoav Gallant seen as the main players.
