Jim,
yet he still thinks the war was worthwhile - no argument there - he is entitled to his opinion - that's what it is AN OPINION

The informed, evidence based opinion of an historian is worth more than than any number of uninformed whims founded on nothing but political dogma.

And not just Sheffield.
Can you name a single hhistorian who holds a different view?
No. You have been trying for years.
All you can do is selectively quote Sheffield hoping to misrepresent his actual view.

Either every historian is deluded, or you are Jim.
