America Is the World's Police Force, and Rightfully so! Here's why!
White Europeans and their descendants who founded the USA spent many centuries enslaving the people of the Middle East and Africa. From formal slavery to colonialization to puppet dictators the 'great white West' have taken advantage of their early lead in technology to take advantage of countless millions of Middle Easterners etc.
We've left their civilization in dysfunctional tatters. Their cultures frozen in various forms of arrested development and the descendants of the rotten leaders we imposed on them still with a boot to their throats.
Yes, like it or not, the West and the US are morally responsible to those poor people living in the tatters of once great civilizations, we are responsible to help them in any way we can to break their chains and overcome the monarchies we have supported. We owe them freedom, technological advancement and food and if we cannot help them in their homes we should welcome them into ours!
It's what's right!
