Buy a clue.
Israel cannot afford to let Iran strike first with a nuclear weapon. With all of the rhetoric coming out of that country over the last several decades, there is no reason to believe that Iran is interested in Detente.
If it comes down to it, Israel would be wise to cripple Iran’s nuclear program, even if that means all out war. Civilian casualties are unfortunate, but a fact of war.
If the Iranian civilians cannot control their government, they are going to get exactly what they deserve. I would say the same for any country, including our own.
If given the choice between a city in the U.S. being hit by an Iranian nuke or eradicating the country of Iran from the face of the planet, I would not hesitate to do the latter. I may regret having to perform the action, but I would not think twice about it and I would lose no sleep over it.
Fortunately, life is rarely so “black and white”, and all of this talk is nothing more than talk, IMO, as Israel will most likely never have the fortitude to strike Iran first with the current political climate surrounding her so called “allies”.
Of course Israel cannot afford to let Iran acquire nuclear weapons. It would be utter suicide. I think everybody on these boards would agree with that, given the rhetoric that comes out of the mouths of the mad mullahs. If Iran acquires the bomb, or even looks like it is on the brink of doing so, Israel WILL attack. At the moment they are very aware that if they do that, they will be labelled the aggressor, and their worldwide image, which isn't great as it is, would plummet. (Yes I know this is illogical, given the activities of Hamas et al, but that's how these things work).
At the same time, the West cannot afford to let Iran have nuclear weapons either. It is not in our interests to see a full scale war in the region. Even if we could somehow persuade the Israelis not to attack, allowing Iran to get nuclear weapons would create a nuclear arms race in the region. Iraq would want nuclear weapons as well, Saudi Arabia certainly would, and the result would be a mini cold war in the entire middle east, with the exception that the various controls that were in force to prevent the US and the USSR from starting a full scale nuclear war would not exist. It's an horrific prospect.
So at the moment I think these actions by the US and UK are perfectly reasonable. The US and the EU have imposed a series of economic sanctions that must be biting the Iranians. That MIGHT be enough to persuade them to pull back from this nuclear development project, which will hopefully quieten everything down. I know that might not work, but we surely have to give it a chance. The alternative will be a preemptive strike by Israel that will lead directly to war, or an Iranian nuclear weapon that will lead inevitably to war, probably with Israel, possibly with other of the middle east powers.
And I would suggest those who wish nuclear destruction on others check their consciences. War may be inevitable. It might be justifiable. It might even be the wisest course of action, given the alternatives, but it is never the optimal solution. I'm not in any rush to kill large numbers of my fellow Human beings, particularly as there is a chance I might get killed myself. It might be neccesary to fight a war, but nobody in their right minds WANTS to fight one.
