Not wanting to get all political on youse..though just to guage your reactions to this.
BBC NEWS | World | Middle East | Israel 'ready to act' over Iran
Wonder what this means..has Bush been wanting this all along..Israel to be drawn into the conflict..so the US will take Israel's side..Palestinines taking Irans side.
Global meltdown in the middle east..sparking a third world war. 
Just a sensible non-political discussion here.
I doubt there would be such consequences as a third world war. Sure, China and Russia will stand against any action the US or Isreal see fit to impose on Iran as predicted, but they are both a long way from going down the road of conflict against anyone who messes with Iran.
I believe that all warring nations at worst, would push for, or try to impose their own way of life on a potential foe. The west hide behind the 'democracy' tag. But I doubt any country would want to wipe the planet out. Iran may have some nasty weapons but they have no decent delivery system. Isreal may take a hit or two but anything 1000 miles plus away is probably way out of reach of Iran's weapons. The concerns of the west towards the likes of Iran and North Korea, is that they may have the bomb. And as each year goes by, surely it's more opportunity for the said states to reach the point of achieving a delivery system for their bombs that make any conflict, a wider incident.
Politics these days is simply a game of bluff. We call their bluff, they call ours. But what I believe, is that the longer we sit on the sidelines and watch from afar, the harder it will be to remedy a political crisis. We did that at the beginning of World War II by declaring war on Germany, and doing bugger all for almost 2 years. If we were more swift, we may well have reduced the 58 million deaths that resulted from that war, and reduced the years it ran for.
Take Iraq. People seem to be in agreement that we shouldn't be there. That we are interfering. But the otherside of the coin, we will never know. But who's to say that if left alone, Iraq, and Sadam may well have developed weapons that could reach any target on earth. Of course, that is hypothetical, but if we had done nothing back when we went in, would we be all sat here now saying, 'We should have gone in earlier and stopped all this before it got out of hand.' We will never know. Again, hypothetically, a few thousand servicemen die in a prolonged war as we have had, or how about Sadam being left alone to develop his weaponry and he wreaks havoc on the worlds cities.
People just agree that we shouldn't be there. But no body ever thinks of any potential reprocussions if we had done nothing. I'm not saying we should be there or not. But political correctness these days seem to blatently shout about what is wrong with society. How we should do this, or how we should'nt do that. Even if such wrongs benefit society and make daily life more bareable.
If left alone, who knows what Iran may be capable of in just a few short years. One thing we definately know though, is that they certainly won't be moving backwards. They of course will be moving forwards, and pushing for the things that will secure their way of life. And that will make things so much harder to remedy, the longer we remain inactive.
