Of course there isNo, there isn't.
Also, what "war crimes" would you like to see Mr Blair indicted on?
Whether or not I would like to see Blair indicted is not the issue. At issue is your silly logic that he can't be because the Brittish people supported the Iraqi invasion
If having a population support an invasion is enough of a reason not to allow somebody to be indicted on war crimes, the Nazi leaders would not have been indicted. You're silly.
