Should Bush and Blair be tried for war crimes?

[Gandalf]

I've been reading with interest about the Chilcot Inquiry into the war in Iraq and it all sounds rather unpleasant. All the negative things that many of us felt about the war in Iraq appear to be turning out to be all too true. The entire thing was founded on lies and deception and it has resulted in the death of over half a million innocent people.

So my question is a simple one. Should Bush and Blair be tried for war crimes?
