Snooping is so easy now in the information age that it is almost inevitable that governments will snoop.
What seems to annoy other nations most is that the USA is better at it than they are.
When snooping is uncovered it always creates a diplomatic row but it doesn't stop the snooping.
At the end of the day I don't believe that USA or the West in general has a malevolent agenda WRT the rest of the world so it does not worry me too much that they are also the best at snooping.
Also Islamic terrorism, like all brands of terrorism, has numbered days and will ultimately fade out.
The west's social and political model sets an example based on capitalist free trade within a socially responsible framework, transparent democracy and freedom of thought and expression which, I think, the rest of the world envies and will ultimately emulate.
