Bush's war in Iraq is famously called an oil war but it's actually more complicated than that.
It was such a fuck up that the US companies barely made any oil contract before Obama's election.
Dick Cheney's former company did make some contracts but it wasn't really about oil.
Bush had no idea what he was doing there and then. I think it's the same for Trump.
And there is pretty much no deep difference when you look at it. It could very well be described as just another US war.
When you trigger a war, you actually don't know how it's gonna play out and they technically have 4 years to wrap it up before the next presidential elections.
But the most important factor is that leaders who trigger wars are deeply retarded.
Afghanistan war was initially called "Operation Infinite Justice" but quickly renamed "Enduring Freedom".
Iraq war was initially named "Operation Iraqi Freedom".
