"Even if we reach a situation in which we are too late and Iran already has nuclear weapons, it does not mean this situation will remain forever," former IAF commander Ido Nehushtan said at a cultural event in Beersheba on Saturday according to Israel Radio.
Nehushtan also asserted that both carrots and sticks are needed in nuclear talks with Iran - sanctions alone are not enough, and it is therefore important to have a real threat of a military strike against Tehran.
The former IAF chief stressed the strike itself is not the goal, it is a means to an end.
"No one wants [to use] the military option. [A strike] happens when the alternative is worse. There is no knowing what will happen following a military strike."
