I'm not sure about extraterrestrial infiltration (though I wouldn't dismiss it), but I do think there are shadowy figures (whether they are alien/human hybrids or not) behind the scenes who are more powerful than any government. For example, it seems odd that Britain and the USA are backing the rebels in Syria, when half of these rebels have the same world-view as al-Qaeda. There's even been reports that Israel is helping Syrian Islamic fundamentalist rebels in their fight to overthrow Assad. There's obviously more to these things than meets the eye.
