Ah, we're still dealing with the 90's. OK, I can understand why you would automatically assume that's what this is for. I disagree with the belief this is rooted in economic espionage. Was hoping for something more modern, but I won't try to change your mind.
How could you since you haven't presented any real arguments? The case for economic espionage is very plausible:
- Historical precedent
- Close cooperation between NSA and US companies
- Spying concentrated on west and south Germany, where the industry is
- Spying at the same level as other economic rivals such as China
- No other real reason to spy on Germany at that level. There is no threat to global peace and stability emanating from Germany
