Yes, redefining terms allows you to consider "scaling back" to mean something that it does not mean.
I fail to see how an examination of the real process of exploration as it actually happened embodies ignorance. Your claim about its expense and profitability only serves to undermine the point that a wider field for production would be an immediate solution. It was not a solution in the past - it already failed to provide energy independence.
There is no reason to insist on partisan scapegoating on this issue. The sitting president is always blamed, and yet the same problems keep arising. Consider that current American oil production is simply not conducted in the interests of domestic consumer price advantage. It is unreasonable to blame Obama for a corporate failure to expand coastal production during the decades before he came to office - the profitability of the status quo had been perfectly fine without such expansion, and thus they never did so when the option was available. This appears as a crisis in a periodic fashion, as production simply can't fall into place immediately, but the time to scapegoat is always at hand.
The fundamental problem is the focus of American energy policy. Energy independence means a surplus of available production, which is not going to be immediately profitable, and thus has never been undertaken in advance. The material opportunity was wide open, but intentionally avoided, and now consumers pay the price.
It's not a partisan issue, and not one specific to any particular moment in time.
