The Offshore Drilling Ban that is in place today has been existence for 30 years. And while part of that ban was lifted last year, there has not been activity in those areas.
As for the moratorium on Gulf drilling after the BP disaster, it was a necessary action at the time, but should have been lifted sooner.
The whole idea that we are not drilling in the US is complete BS and the idea that we are not producing oil is nonsense as only Saudi Arabia and Russia produce more oil.
