Some 72 percent of Israelis support the use of nuclear weapons in certain circumstances, according to the results of a Canadian survey released Monday, Army Radio reported.

The number of Israeli respondents in favor of destroying the world's nuclear arms was lower than any of the six countries questioned in the Canadian Institute of Strategic Studies poll, the radio said.

Pollsters said the Israeli response demonstrated that the public is primarily concerned with national defense mechanisms in the face of a threat from a nuclear Iran.

About half of the Israeli respondents who back using nuclear weapons said they saw it as a possible way of preventing war; the other half said they supported using nuclear arms during a war.

The poll also showed that 75 percent of Israelis would feel safer if they knew with certainty that Israel has atomic weapons. Israel has maintained an official veil of secrecy on rumors that it has in its possession nuclear weapons.
