Jim,
The war was an Imperialist one - Britain showed no interest in what was happening to the people of Germany

Nonsense.
That is also the standard communist propaganda line on WW1.
That is nonsense too.

We declared war on Germany in 1914 because they refused the ultimatum to withdraw their invading troops from Belgium, and in 1939 because they refused the ultimatum to withdraw their invading troops from Poland.
