"One of Israel’s most senior military officers has said there is no obvious alternative to Hamas’s rule in Gaza and that deposing the Islamist group in the coastal strip cannot be achieved quickly."

"Contradicting claims by leading political figures – including Israel’s prime minister, Binyamin Netanyahu – Turgeman said that far from forming an ideological axis with Islamic State and al-Qaida, Hamas “does not want global jihad” and had shared interests with Israel, not least stability."

"The only replacement for Hamas is the IDF [Israel Defence Forces] and authoritarian chaos. Other than Hamas there is no other axis that could control [Gaza].”
Turgeman added: “The [Palestinian] Authority cannot rule and this should be taken as an indisputable statement.”
