Superman Sheffield, the establishment spokesman on the war

Canadian Margaret Macmillan is in complete agreement with him on these issues.
Likewise US historian Max Boot.
Also Catriona Pennel, and every other historian who has written on it.

There is no "establishment" view of these century old events.
People learn their history from historians.
Suggesting that historians lie for "political expediency" or collude in
falsifying research (and somehow hiding that from their students) is ludicrous and shows that you have nothing whatsoever to support your deluded, political version of history.
