It would reign in what Blair is doing now (in fact I reckon it would probably have forced him out of office by now), but I don't think that anything would have changed on the war front if PR had been used (and I assume introduced) at the last general election.
I agree it wouldn't have had that effect if hypothetically introduced at the last election. But lets suppose UK had always been under PR. And then lets take two important events in the Iraq story.
-The private meeting meeting of Blair and Bush where the decision to go for Iraq was atleast provisonally made by our PM.
-The parliamentary vote to endorse the war.
On the first, you're right, it would not have been "impossible" for Blair to make that decision. Under PR he would perhaps have been more aware of the political risks of such a decision, (even with a large majority), but he would have reasoned that there was a legitimate route to war (through the UN), and he had at that stage no reason to believe that such a war would be unpopular.
On the second, IMO Government would have been at risk of collapse. Proportionality would have narrowed the difference between the parties in the first instance. This would then have put the electoral discipline outlined in post 12 in to play.
By the time of the parliamentary vote it was becoming clear that Iraq II would be an unpopular war. It is reasonable to suppose that a greater number of Labour MPs (more than 122 who voted against) would have considered the electoral risk of their Government's policy.
Two options would have been open to them.
Back the Government and hope for best at an election, which under PR doesn't protect majorities as under FPTP.
Or bring down the Government and form a coalition with parties opposed to the policy.
This is the structural effect of PR. Better representation becomes better accountability. Where a Government's survival depends not just on a five yearly ballot box tick, but on their continual capacity to justify policy in accordance with the pubic interest. They failed to do so with Iraq II. There might have been consequences under PR.
