One day last week, she strode across the stage during a tour of the site at Jerusalem’s Mount Herzl, flanked by reporters and television cameras. A former brigadier general in the Israeli military, she told the chief engineer that she wanted “zero casualties” in this event. In 2012, an Israeli Army officer was killed during a rehearsal for the ceremony’s flag parade when a lighting rig fell on her.

On the way out Ms. Regev instructed an aide to check on the number of portable toilets and quantity of toilet paper, so there wouldn’t be problems like in the past. “Write that down!” she said.

“This will be a breathtaking display, the likes of which we have never seen before in Israel,” she told reporters.

But many people apportion much of the blame for the brouhaha on her campaign to have her patron, Mr. Netanyahu, lead the ceremony instead of Mr. Edelstein, whom Ms. Regev views as a potential rival within Likud.

Mr. Edelstein said he would boycott the ceremony if Mr. Netanyahu gave the keynote speech. Carmi Gillon, a former chief of Israel’s Shin Bet internal security agency, called on Israelis to switch off their televisions while Mr. Netanyahu spoke. Netanyahu supporters said Mr. Gillon should be the last person to preach about prime ministers, since Prime Minister Yitzhak Rabin was assassinated on his watch.

Last week, the two sides announced a compromise that was to have ended the feud.

The prime minister’s office said that Mr. Netanyahu would light one of 12 torches, representing the 12 tribes of Israel, in the name of all the governments of Israel and, like the other torch lighters, make brief remarks relating to Israel’s Declaration of Independence.
