This is a joke... right?
We did not go into Iraq for oil. If all we wanted was oil we could have secured it with almost no casualties, and we were in such an oil crisis as to require invasion to avert it we would have instead of a mere 25% of the U.S. Army deployed to Iraq the entire U.S. Army would have been deployed.
A war for oil sees U.S. Divisions guarding a ring of death around the oil fields, with U.S. contractors busily pumping oil into freighters escorted by heavy cruisers and the persian gulf walled off with Aircraft Carriers. As well as any ship and/or structure within 2 miles of the coast annihilated by air-strikes.
No human being allowed within 5 miles of the oil fields, and absolutely no news coverage of events. On pain of death.
The rest of Iraq be damned.
That's what a war for oil looks like.
No need to overthrow Saddam, or fight and insurgency, if a City is in the way of the supply route and there is a genuine oil crisis the likes of which America will cease to exist? A couple squadrons of B-52's will remove that problem.
Now. Why do people claim that the U.S. and our allies went into Iraq for simply oil? Because its an easy inflammatory comment that denies logic and is easy to believe by masses of stupid people who never studied Philosopy nor Military tactics or History in the least.
Personally I believe the war in Iraq is a good thing. My Father was over there, half a dozen of my closest friends have served tours over there.
We're building an entire country, whole cities at a time, up from scratch, and essentially taking millions of people out of the Third World and putting them in the First World. If anything Iraq is the single greatest Humanitarian effort of this Millenium. (Boy that sounds cool.)
More's the point it is easily definable as a Just War. (I've written an Essay on it using the Just War Theory for Ethics. I got a B in Ethics BTW. If you want me to post it just say so.)
Now the real question to ponder isn't why people hate the idea of going to war for oil so much. But what would be their opinions if America needed to invade someone to maintain its standard of living through taking oil by force?
That's a much better question to ask, and a very interesting scenario to ponder.
