You're talking about nationalizing our oil industry. Which would be great if it really worked (historic inefficiency and lack of competitiveness) or if it were even workable in the first place in the US.
Well, lets see. We're the No.1 consumer of oil -- with a bullet -- so to speak. About four times more than anyone else (Millions of barrels per day): 
United States: 19.993 (actually 21 now)
Japan: 5.423 
China: 4.854 
Germany: 2.814 
Russia: 2.531 
But we are ranked 16th from the standpoint of reserves. 
1  World 1,025,000,000,000 
2  Saudi Arabia 261,700,000,000 
3  Canada 178,900,000,000 
4  Iran 130,800,000,000 
5  Iraq 112,500,000,000 
6  United Arab Emirates 97,800,000,000 
7  Kuwait 96,500,000,000 
8  Venezuela 78,000,000,000 
9  Russia 69,000,000,000 
10  Libya 38,000,000,000 
11  Nigeria 34,000,000,000 
12  European Union 28,210,000,000 
13  Kazakhstan 26,000,000,000 
14  United Kingdom 25,410,000,000 
15  Angola 22,880,000,000 
16  United States 22,450,000,000 
Now, I don't believe this takes into account tar sands and deep gulf and the difficult fields under the great plains that are viable at $40+ per bbl oil. But, since it costs the Saudi's about $5 per bbl to produce their crude you had better really hope we don't enter another oil glut at any point in the near future if you are an investor, or if you are a taxpayer and we have nationalized the industry. ANWR, is literally a drop in the bucket whether it is included in the above figure or not.
We are currently producing oil at a rate second only to the Saudi's (millions of barrels per day):
Saudi Arabia: 8.528 
United States: 8.091 
Russia: 7.014 
Iran: 3.775 
Mexico: 3.560 
Norway: 3.408 
China: 3.297 
Venezuela: 3.137 
And yet we can only meet about 45 percent of our demand. If we more than doubled our production (probably take 10-20 years) our reserves which are scheduled to last 12 years will only last 3-4, but it wouldn't matter since we couldn't increase that production by the time they will run out at current rates. Saudi will have cheap oil for 81 years by comparison.
Now, this is based on economic (cheap) oil. We can easily produce oil at 8 times the cost to produce it in the areas with the greatest reserves. So, we can easily have more expensive oil than the rest of the world by a huge margin from many decades. Remember, current $100 bbl oil is based on a subtle shift in supply and demand, market speculation and some 30 percent the devaluation of the US dollar. It is not only possible, but highly likely that we will shortly see oil well below current prices unless OPEC really hauls down production. 
But, if they did so they would be endangering their position by encouraging additional supply that will ultimately chip away at their dominance. Perhaps just slightly but it doesn't take much -- only a few percent relative to supply and demand not even counting "uneconomic" oil. And of course, there are other players beyond OPEC who will undersell (increase production) them at some point, and usually things collaspe like a house of cards at that point. We can produce $40 or $50 or $60 per bbl oil if we have to all day long. But, they can just as easily maintain $20-$30 a bbl oil with healthy profits and make our investment in tar sands etc,. non viable. It's all a balancing act.
There is a reason why things are the way they are.
