^ The Olmert comment was a slip-up on his part. Yes, while Israel has not willingly said "we have nukes", everybody knows they do - Vanunu made that rather clear to the Sunday Times in 1986.
A slip up that confirmed something long suspected. If ahmedinejad would say "oh yes, we have a facility that produces HEU and have enough material for 5 nukes" would that be treated as a slip and dismissed as such or a confirmation of Iranian nukes and used to "do something about it"?
