A McCain Presidency Mean War?

Will a McCain Presidency mean war? It follows logically that if McCain is elected that he will follow President Bush's foreign policies, which means that a missile shield will be installed in Poland and elsewhere. That means a serious confrontation with Russia. I am not standing up for Russia but I have to wonder why the U.S. is putting up a missile shield to protect Europe when Europe itself is not pushing for it. Why does Europe need to be protected from North Korea and Iran? There have been no threats against Europe by these countries and there are no apparent logical reasons for any threats to be made by these particular countries against Europe.
The lack of reasons or logic is bound to make Russia suspicious of U.S. intentions and the rhetoric spouted by the neo-cons is far from assuring to anybody, Russian or American. McCain's intentions in this area needs to be scrutinized closely. So far no one has asked McCain what his intentions are in this area. With the World's future at stake it would seem that someone would ask McCain about missiles defense in Europe wouldn't you think?
