There is no simple, overall, constant policy like containment was toward the USSR for its final roughly forty years of existence. But there is a systematic set of nearly absolute goals which are interrelated. Let me set them out a bit starkly and clearly.
1. The U.S. will do whatever is necessary, if possible, to keep the Saudi and Persian Gulf oil flowing at its current rate.
2. The U.S. will protect Israel to keep it going.
3. The U.S. will contain Iran, work to decrease its wealth and power, carry out cyber and spy attacks on vital industries like nuclear enrichment and encourage revolutions against the government to bring it down and put a pro-U.S. one in place.
5. The U.S. will accept new pro-American regimes when necessary and work to make them more so in every way to control the oil and other vital resources.
