The reason is that UK money invested in diplo is usually money that wouldn't be invested in the defense of France anyway (unlike Germany expenditures).
And the french money? Imho not to waste their money or to find better investments than their possibly lost cause is the only reason for uber. Otherwise, I could imagine other opportunities to invest.
Blitz is one possible solution. It could also be a chance for the Axis to waste even more money to counter uber...
Uber bears high risks. If the Brits don`t succeed (which means to achieve more and bigger hits than average), they're probably screwed.
