ElBaradei says nuclear Israel number one threat to Mideast: report_English_Xinhua
El Baradei may well be correct in stating that Israel has Nuclear weapons.
What he failed to mention is that Israel has since it's inception not waged an offensive war against any other Nation.
Nor indeed has it threatened any other Nation with it's supposed Nuclear weapons.
Israel has most certainly never threatened to wipe another Nation from the face of the map.
