The American healthcare debate is not a debate for Americans only. In two ways at least, the debate implicates the well-being of everybody in the developed world. More money spent on healthcare means less money for drug innovation -- a U.S. speciality that services the world. It also means less money for American defence -- something U.S. allies might be less than pleased with. Because when Americans talk about today's health costs, they are also talking about tomorrow's defense budget -- the budget that protects us all from a world of dangers.
