With respect, what Tony Blair has personally put on the line is as mooncast shadow compared to what the troops are putting on the line. Sure, Tony may lose his job as result of what he has done for us, which does count as a high level of courage when it comes to politicians. But the real measure of Blair's resolve should be gleaned from the fact that he is willing to see young Brits die (which is going to happen) in order to put Hussein out of business.
How does this differ from any other war leader?
