A New Population Bomb

Love VDH's use of the term in this column. Not a "bomb" of overpopulation that destroys a nation from within, but a "bomb" of ideas and hands that prepares a nation for global competition
Is there any major domestic problem we in the West currently face that isn't in some way tied to abortion and birth control. . .or more specifically, to the fact that 1/3 of our productive citizens ain't here? Just asking.
