Who was more hated during their reign: Tony Blair or Margret Thatcher?

Thatcher was a Cold War prime minister. Surely the threat of all-out nuclear war was a little more consequential than anything Al Qaeda could throw at us? Also Thatcher was almost blown up by the IRA. Also, during her time sovereign British territory was invaded by a foreign power.

But these things are all "easy" from a policy point of view. Clear-cut enemies who can be painted as being in the wrong very easily, making aggression on the PM's part much easier to justify.

I think I agree with the idea that Blair got out of his depth.

in the sense of cosying up to W or in the sense of developing a mesianic streak after kosvo intervention?

not that those thing are necessarily exclusive. thinking he could bend wolfowitz and cheney et al to his will i guess his biggest mistake. but it's all there in the 1997 manifesto: whatever works innit.
