It would be straightforward, if the situation were static.  It isn't.  

The question, (which Sky-King chickened out of addressing) is whether there is an amount of INCREASE which is too great a burden to be borne.  Would any of you "pro-military-at-any-price" people care to take that question head-on?  Or would you rather have me just assume I know what you'd really think, but lack the strength of character to admit?  YOUR CHOICE.
