No it doesn't - these are not mutually exclusive choice. How are expenses for US health care and aid to foreign countries related? You could just as well budget the money for the latter against the expense for a coffee, an aircraft carrier or Armstrong's salary.
I totally agree that health care is too expensive at the moment.
I am hopeful that this is not a zero-sum game...
And for the record, I think this is the wrong battle, health care is entirely too expensive in the first place.
