And the reason for Brit offense over Argo is pretty tenuous. Seems more like a matter of perspective than insult.
What pissed us off about SPR was the British were mentioned only to slag them off, the Monty comment. And btw, it was the Royal Navy that landed the US troops on that beach, as they did almost all allied troops: 79% of all ship son D Day were British (50% of all air cover).
The Canadians are the ones who should feel slighted by Argo.
