Take Blair and Iraq. The people told him not to go to war. He ignored them. The people of Iraq are now much worse off. Last week he said he still wants Britain to have full defence capablity and be able to make more wars. He also wants a new generation of Trident (WMD) too.
Let's imagine a child. This child wants to play with a dangerous toy. You say "Not a good idea," but he does so anyway, and burns the neighbour's house down. Then he says "Want to play more with it."
Would you say the boy was stupid? Would you take the toy away?
If the boy was a man, would you say that describing his behaviour as psychopathic was accurate?
What's the difference between this boy/man's behaviour and Blair's?
