Questioning the official reason for war with Nazi Germany ≠ Support for Hitler.
If saving Poland was our real purpose, then not only did we fail but we sacrificed the lives of a million British and Commonwealth soldiers & civilians and incurred massive national debt for nothing.
That's as may be but I am sceptical about the official reasons for entering both world wars.
All wars are bankers' wars.
The noble reasons given are excuses to whip up public support.
If saving Poland was the our real reason for fighting Hitler, then we failed miserably.
