Former IDF chief of staff Lt.-Gen. (Res.) Moshe Ya'alon said Friday that Western nations and Israel have the ability to launch a military strike that will set back Iran's nuclear program for many years. Ya'alon, who retired last June after a 37-year military career, told an audience in Washington on Thursday that Israel had the capacity to carry out a military strike against Iran by itself. Ya'alon told Channel 1 on Friday that he stood by his earlier comments, but he didn't repeat his reported assertion that Israel had the capacity to attack Iran's nuclear program alone.
