That he posts this kind of thing on twitter like a loose cannon, should, in a sound democracy be enough to start a serious investigation in my opinion. Now Germany won't do much in reaction to this irresponsible display except look bewildered, but he's doing the same effing thing with China and others, and that's just madness.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
