Iran should not sponsor terrorist groups outside its own borders.
Exactly, Steve! Israel does not do this, in fact they clamp down on any terrorist groups in their country.
Israel is an ally of the west.
Israel has killed Brits in the past, but mainly after the forming of their state around 1948 I believe while the British were sill in their country.
There have been Israeli attacks by extremist groups in America in the eighties, but not endorsed by israel its self.
Israel supports no terrorist groups. And they are not against ordinary muslims like shia or sunni, only terrorist groups like Hamas in Palestine and Hezbolah in the Lebanon. Indeed any religion is allowed in Israel, although most Israelis are Jewish!
And yes, about 90% of muslims are peacefull, but the ones carrying out the terrorist attacks in the west do so because they think the west is corrupt, and their aim is to take over and set up a Caliphate, that is a muslim government.
I believe Iran is responsible for the majority of attempted attacks on the UK!
So in response to ngbs post, I would say I certainly feel safer with Israel having nuclear weapons rather than Iran!
