I know that for half a century it has been rumored and even promoted the belief that Israel has nuclear bombs.

This came about through the assistance of the French.

There has been ambiguous threats form Israeli operatives over the years that if Israel ever faced it's destruction it intended to take Western Europe with them.

But this years long turmoil with Iran has caused me to doubt the existence of Israeli nuclear weapons.

Could this be a bluff to blackmail and cause hesitation on the part of Israel's enemies ? If they had these weapons how come they did not use them in the 6 Days War or against Egypt.

I think the existence of these weapons are a bluff.
