Go to Europe and raise some spirits with a speech at Brandenburg Gate.  A nice idea, I guess, because:

John F. Kennedy visited the Brandenburg Gate after declaring "ich bin ein Berliner" in 1963. Ronald Reagan stood at the gate in 1987 and challenged Soviet leader Mikhail Gorbachev to "tear down this wall."

I heard of the plan a while ago and actually thought Barack might be overdoing the JFK thing.  Apparently it is a nice place to give a speech, though, so whatever...

Of course, some pipsqueak thought it might make him look a bit too presidential, however:

Report: Bush Privately Told Germany He Had Misgivings About Obama Speech

OK, it might not have actually been him:

Today, Der Spiegel reports that Bush administration officials privately told the German government that they don't like the idea:

The respected Frankfurter Allgemeine Zeitung newspaper reported this week that a member of the Bush delegation approached Merkel's foreign policy advisor, Christoph Heusgen, at the G-8 summit in Japan to discuss misgivings about Obama's planned speech.

Yeah, you wouldn't want to have some foreign country influencing how our candidates are perceived:

When McCain travelled to Colombia last week, the government there shared with him the minute details of the freeing of hostage Ingrid Betancourt -- and they also helped to assure that his appearance came off as very presidential.

...unless it's going your way, apparently...
