Politicians are under the microscope by a largely cynical public who don't want to be invaded. The next round of elections in any country that's taken in millions over the past few years will be interesting - unless of course they all get granted immediate citizenship so incumbants can buy votes.
But yep, most people know what's going on, and unless you're some sort of Marxist freak you're not too happy about it.
