Oh OK sorry I'm not a native English speaker so I might not chose the right words.

I was asking who spontaneously changes their mind without any event that would trigger such a change? If I believe in something, why would I have any motivation to change it if everything is running well / as planned?

Oh it's mostly a figure of speech - the point was that Germans 'changing their mind' was not anything close to 'spontaneous' despite the fact most of it was, over the long term, arduously accomplished by Germans themselves.
