lol! A better question might be what war won't he start. He certainly has his eye on Iran.
McCain clearly buys into the Neo-Conservative nonsense of US global hegemony, fighting wars to impose democracy and for the benefit of other countries.
The only reason I can see to vote for him would be to keep the messiah/cypher, Obama, out of office. Not a bad reason but a McCain presidency is still something to be feared.
Enough of this empire and perpetual war for perpetual peace crap.
