JERUSALEM — The fighting is barely over in the latest Gaza war, with a five-day cease-fire taking hold on Thursday, but attention has already shifted to the legal battlefield as Israel gears up to defend itself against international allegations of possible war crimes in the monthlong conflict.

Israel has excoriated the United Nations Human Rights Council over the appointment of Prof. William Schabas, a Canadian expert in international law, to head the council’s commission of inquiry for Israel’s military operations in the Gaza Strip.

The broader struggle will be over what some experts describe as Israel’s “creative” interpretation of international law for dealing with asymmetric warfare in an urban environment. More than 1,900 Palestinians were killed in the recent fighting, a majority of them believed to be civilians, while on the Israeli side 64 soldiers and three civilians were killed.

Israeli leaders view the Human Rights Council as hopelessly biased against Israel and say statements made in the past by Professor Schabas rule him out as a fair adjudicator. In one prime example, Professor Schabas was filmed in New York almost two years ago saying Prime Minister Benjamin Netanyahu was his “favorite” to be in the dock at the International Criminal Court.
