Which wars did the US start on a lie for oil ?
You could easily argue that most of the conflict the US is currently involved in - and there are many! with boots on the ground or otherwise[0] - have some motive involving petrodollar or other resources. [0] https://www.pri.org/stories/2014-09-16/us-now-involved-134-w...
Highly respected, four star general, Wesley Clark says that the Iraq war was about attempting to strip Russian influence out of the Middle East. That the plan was to knock over several of the dictatorships there, which were overwhelmingly friendly toward Russia and hostile toward the US and its allies.
You're saying it was about oil primarily. Yet the US didn't take Iraq's oil. The US didn't even secure an outsized share of contracts related to Iraq's oil. The US vaporized a trillion dollars, along with suffering tens of thousands of wounded soldiers, trying to stop the Iraqi civil war in which Iraqis killed hundreds of thousands of each other.
Simultaneously over that decade the US technologically unlocks its massive shale oil resources, making Middle Eastern oil almost entirely moot strategically. So much so, that the US is now merely about 10% of Saudi oil demand.
And the US got what out of all of that Iraq mess when it comes to oil? The US stuck its military where it shouldn't have been, and it did so for geo-political reasons, not economic reasons. The US was a massive loser economically from that effort to try to weaken Russia, it was an economic disaster. The net 'benefit' over two decades will be perhaps close to a negative two trillion dollars all-in.
