Fundamentally, Henry Dawson did it all for 'the little ones'

Henry Dawson's other Manhattan Project wasn't really to advance the cause of penicillin, to aid the Allied military effort or even to save the SBEs : rather he did it all for 'the little ones', to persuade Humanity to build a "Big Tent" that included everyone.

For with rare exceptions (perhaps the early days of the Communist revolutions in some countries) a Big Tent doesn't need to invite the big and the powerful inside - for they are already there.

Instead a Big Tent always newly invites in the small, the weak, those traditionally judged unworthy and unfit.
