--1997 DOD briefing--
It is interesting to note that we have not yet spent near $400B on the F-35. For development and LRIP we are well on our way to spending around $60B since the JSF concept started in the 1990s.
McCain is probably correct:
McCain, again quoting AOL Defense, said "that the path we are on is neither affordable nor sustainable... If things do not improve -- quickly -- tax payers and the war fighter will insist that all options will be on the table. And they should be. We can not continue on this path."
We still have a chance to stop the bleeding.
