TEL AVIV  In the year since Israel launched its devastating military offensive against Hamas in Gaza, the country’s political and military leaders have faced intense international condemnation and accusations of possible war crimes.

But Israel seems to have few qualms. Officials and experts familiar with the country’s military doctrine say that given the growing threats from Iranian-backed militant organizations both in Gaza and in Lebanon, Israel will probably find itself fighting another, similar kind of war.

Only next time, some here suggest, Israel will apply more force.

“The next round will be different, but not in the way people think,” said Giora Eiland, a retired major general and former chief of Israel’s National Security Council. “The only way to be successful is to take much harsher action.”

Such talk has raised alarm among some critics in Israel, but so far it has stirred little public debate.
