Regime Change should prove a useful book for anyone wishing to understand the crisis in Iraq. It is an account of the world since 9/11 and of the arguments for and against America's new militancy. It is also a coruscating attack on those the author sees as having betrayed and confused Western liberal values through their failure to recognize the unique threat posed by Islamic fundamentalism. The forcible regime change in Iraq is the crucial issue of the book - but it also suggests that, equally, we must all undergo our own intellectual regime change and seriously get to grips with what we now face.
