Wars the US waged in Iraq, Afghanistan, Syria, Yemen, and Pakistan following September 11, 2001 caused at least 4.5 million deaths and displaced 38 to 60 million people, with 7.6 million children starving today, according to studies by Brown University.
Ya, America saw a rising star in Africa, couldn't exploit it, and kicked it over a millenia into the past. You aren't allowed to prosper unless American corporations get the biggest slice of your pie.
Millions might have died but a few arms dealers made a lot of money so who can really say if the wars were good or bad?
