Was John McCain Right About Obama's Speech?

Yesterday, during a campaign stop at "Schmidt's Sausage Haus und Restaurant", John McCain criticized Barack Obama's speech before 200,000 people at Berlin's Victory Column, saying:

Well, I’d love to give a speech in Germany, a political speech, or a speech that maybe the German people would be interested in, but I’d much prefer to do it as president of the United States rather than as a candidate for the office of presidency.

Does John McCain have a valid point? Or, could it be argued that while there aren't any electoral votes to be won in Germany, we do have many shared interests that need our attention? And given that Germany is a friend to our country, wasn't Obama's speech both necessary and appropriate?

Let's check with noted foreign policy expert, Senator John McCain:

There aren't any electoral votes to be won up here in the middle of a presidential election. But there are many shared interests that require our attention today, and many Canadians here I am proud to call friends.

Uh oh. Does that mean John McCain isn't proud to call Germans his friends? Or was he just having some whine with his sausage?
