Since when?When it was the so called communist, the anti Vietnam war activists, the Black Panther activists, who cared? Now it is a big thing? There is not much difference between the West propaganda ( lazy journalists: CNN, BBC etc... ) and the North Korea´s Communist party brain wash.
Spying for the current economic war ( a war the USA could lose in the near future, if European leaders do get wiser than the 21 century tea party fools ), not much about terrorism.
Almost every country spy on other.
