Did you know that about the same number of people died because of the Vietnam War as have died because of the Iraq War? That death count is a bit over a million for each war.
The main difference is that a fair number of those Vietnam War deaths were US soldiers whereas only a tiny fraction of Iraq War deaths have been US soldiers. The other difference is that the Vietnam War included a mainstream media that did its job by regularly reporting those deaths, the very thing the present mainstream media fails to do.
As long as Americans aren’t dying and don’t have to be reminded about those who are dying, most Americans don’t care and often get irritable if anyone suggests they should care. The US government could kill millions more innocent people and it still wouldn’t break through the moral indifference and blissful ignorance of the American public.
That is the brilliance of the elite in ruling the American empire. They’ve figured out how to keep the imperial subjects unaware and docile, even in this age of mass media where so much info is available.
