That's fair enough, if countries sign up to 2% GDP they should stick to it. However, before send daft invoices, Trump should remember there are other forms of contribution apart from cash. How many military bases does the US have in Germany? They aren't just there for the defence of Germany. If it came to a land war between the US and the Russians, Germany's major contribution would be to provide the pitch.
