A friend once told me that the Viet Nam Conflict was a cunning ruse on behalf of the South Vietnamese to steal 60 thousand American Jeeps.
The daleks were the Masters of the Earth for a full decade of the 22nd century and then lost everything very, very quickly.
How much of the technology there after was bases on Dalekanian design?
How much of their architecture was left intact and seen as "usable" despite the ick factor.
Children using hollowed out Daleks instead of Bicycles to go to school in?
Speaking of kids.
Can you imagine them playing marbles with Dalek bumps?
