What can Germany learn  from America ?

I'm in Cologne, Germany doing an interview. I was asked -

What should Ms Merkel do and What can Germany learn
from America ?

The UK and the US are turning more and more into surveillance states, and cracking down on whistleblowers. Merkel should take the lead in opposing this trend: Germany should protect privacy and work to end surveillance.  Germany should protect whistleblowers and offer them asylum.

What Germany can learn from America:

There are lots of positive things Germany can learn from America: such as the First Amendment. Both countries have learned a lot from each other already.
But Germany can also learn from America's mistakes! Germany can learn not to start wars all over the world!
