Israel has had nucleur weapons since about 1969. Israel has never used nukes, and has never even threatened to use nukes, despite being in very serious trouble in the early stages of the 1973 Yom Kippur War.
In other words, Israel has proven to be a responsible nucleur power........as would be expected of a democratic western nation.........
Iran, on the other hand, is ruled by loonies.
The difference between allowing Israel to have nukes and allowing Iran to have nukes is the difference between allowing the mature, upstanding gentleman down the street to have a shotgun.............and allowing the neighbourhood 15 year old nutbar that cuts himself, threatens his neighbours, and beats up his sisters to have a shotgun.
You're going to cry when Israel gets its dusting Colpy, and it will happen because its sacrifice is in the cards. It has just about served its purpose. The majority of the worlds Jews do not consider Israel the native land. All the immigration into Israel is west bank settler loonies, a viler lot of disgusting cutthroat wackos cannot be found. Amadinejad laughs at them, everyone laughs at their lies now. That's pretty funny froth in your post by the way.
