In today's Guardian Bill Clinton: Trust Tony's judgment:

In the post-cold war world, America and Britain have been in tough positions before: in 1998, when others wanted to lift sanctions on Iraq and we said no; in 1999 when we went into Kosovo to stop ethnic cleansing. In each case, there were voices of dissent. But the British-American partnership and the progress of the world were preserved. Now in another difficult spot, Blair will have to do what he believes to be right. I trust him to do that and hope the British people will too. (via Andrew Sullivan)
