An unsurprising poll from Angus Reid:
'The revelation that there are Russian spies posing as American citizens in the United States did not shock many people in the North American country, according to a poll by Angus Reid Public Opinion. 77 per cent of respondents say they were not surprised about this situation.'
The poll also found that:
'Half of respondents (50%) think Russia should not be singled out for its espionage because many other countries keep active spies elsewhere. One-third of Americans (34%) disagree with this view, and believe Russia should be shamed for maintaining a Cold War mentality by keeping active spies in Western countries.Two thirds of Americans (65%) think the Central Intelligence Agency (CIA) should continue to train and send American spies into other countries, while only 12 per cent believe this activity is no longer necessary.
