I have no reason to believe that claim. The Tories have been behaving in the manner of our Democrat Party. If they win an election on that platform they'll feel no need to reverse course about the war.
Just as Zapatero feels no need to reverse course. Just as Ukraine feels no need to reverse course.
I have no love for the current parties of Labor or Tory, but I do hope Blair wins.
The tories aren't using Iraq as a major policy platform like Schroeder in Germany did.
