Sen. John McCain (R-Ariz.) said he is worried about protectionist and isolationist views taking root in the Republican Party, particularly in the newly elected group of conservative Republicans. McCain said these views might contribute to dwindling GOP support for the war on terrorism.

The younger Paul, McCain said, has already talked about cuts to defense spending, causing the senior Republican to worry.-McCain Worried About ‘Protectionism and Isolationism’ in GOP
So, McCain isn't worried about the cost in dollars and lives of the endless wars that he supports, but that his precious military-industrial complex might have to tighten its belt a little. Sadly, McCain will probably get his wish, and no real cuts in military spending or change in the aggressive and dangerous U.S. foreign policy will occur.
