The Venezuelan oil industry is in big trouble, because the government has not invested in any aspect of oil production or refining. The only reason it still has an industry is because of investments made by privately owned companies before they were nationalized.
Russia has lured in private investors, then ripped them off when it was convenient. Russia is a very risky place to do business, but there is so much oil and gas there that at least some people find it worth the risk.
When you suggest nationalizing oil companies in the US, do you mean all of the hundreds or thousands of individual companies? Or would you just make it impossible for them to operate? It sure seems like your suggestion would lead to the end of the oil industry, not immediately but gradually over a couple decades.
If the government owned the oil industry, and Congress had to decide between 1) investing in exploration, production, refining and pipeline construction, or 2) supporting Social Security and Medicare, what do you think it would do? Actually, I think your answer to that question would be the same as mine.
