Oh well, I'm not clinton fan either.
As to your question, outrage is augmenting at the moment, but I can't see us going to war over this, at very least certainly not on our own.
However, the good result of this, will be when the time comes for us to stand with the states and israel vs iran on their nuclear programme, it will be soooo much more easier to convince the British people.
I would say this however, it's difficult to predict what the Iranians will do, the government here will not wait for ever, and sanctions and blocades are an option, but thats a good few weeks down the line sadly.
I have no doubt Blair would like to do more, but militarily it's incredibly difficult to see it going down that line for some time over this.
