I don't think a member of the Greens can get the job, but Joschka might be a candidate for the EU foreign minister. His most famous quote is from a Bundestag debate, by the way:
"Mit Verlaub, Herr Präsident, sie sind ein Arschloch."
("With all due respect, Mister President, you're an asshole.")

"If you know your enemies and know yourself, you will not be imperiled in a hundred battles." Sun Tzu
