Germany and spying

This refers to the report, "Germany to spy on US: Minister" (July 9). Germany cannot be that naive after it learnt that America's NSA spied on Chancellor Merkel's mobile phone. Germany woke up after one of its agents was selling state secrets to the US in return for cash. In today's world, every nation spies on every other nation and it is an open secret. Conditions after the Second World War were different from existing ones -- there were no internet and mobile phones in those days and the word satellite was alien. The world now cannot exist without these three things.
There was no need for Germany to refrain from spying. Germany has the required technology and is one of the biggest economies of Europe and the nation needs to safeguard its economic interests. Why cannot Europe have one unified spy agency where all European nations will work together and be as powerful as the NSA?
