YES! But this bears question, why is that so?
Why is the US empire (and the US oligarchy) so thirsty for war that it is willing (one could even argue: eager) to sacrifice lives, physical and psychical health of its people (soldiers)? Why is it not putting trillions into infrastructure, health, education instead of spending them to wage wars with nations which have not even thought to attack the US, let alone have done it? (And most of which don't have the resources to do it!)
Well, yes, it is about oil:

But the issue is much deeper. So deep indeed, that I'll (again!) quote a man who knew what he talked about, George F. Kennan: "Were the Soviet Union to sink tomorrow under the waters of the ocean, the American military-industrial establishment would have to go on, substantially unchanged, until some other adversary could be invented. Anything else would be an unacceptable shock to the American economy." (https://en.wikiquote.org/wiki/George_F._Kennan)
So, it is not only the oil (or any other resource to be taken from others). And is is not only about money to be made from bombs (and private contractors who fight, spy, prepare meals for soldiers, wash their uniforms, repair their trucks, build military installations etc.).
It is the US economy at stake.
And that's why you need the POTUS, the Senate, the Congress, intelligence agencies, millitary-intelligence-indutrial complex, the media - to all pull on the same string. And to "invent" enemies: Russia, China, Vietnam, Serbia, North Korea, Cuba, Iran, Syria... or "the Muslims".
But the truth is hidden by the fourth estate from the US citizen with slogans such as "we bring democracy, human rights and freedom to the world", or with self-aggrandizing "American exceptionalism" (cringe!).
