They're probably referencing Iraq and I'm not sure it was raw resource extraction as it was so much removal of a competitor (whatever the name of the Iraqi state oil company was) and more than that, enabling sales of equipment, consulting, etc. It wasn't as simple as some 1800s colonialism, it was advanced wealth extraction worthy of the 21st century.
Ok. So the US spent $3 trillion[0] on a war in Iraq to get some consulting contracts from a country with a GDP of $36 billion[1]? And didn't invade Saudi Arabia, which actually has oil? How much wealth do you estimate the US extacted from the war?
While I don't lend credence to it being that simple, it's worth noting that the people making that profit aren't the ones paying for it, and the ones paying for it aren't using their own money.
