John McCain Does Not Understand Cause and Effect

Others are focusing on the more bizarre moments of Time‘s McCain interview, but I want to highlight a passage near the end. Here’s McCain:

I believe that the world is better off without Saddam Hussein. I believe it’s clear that he had every intention to acquire and use weapons of mass destruction. I can only imagine what Saddam Hussein would be doing with the wealth he would acquire with oil at $110 and $120 a barrel.

Are there any sixth graders available who can explain to John McCain why that last sentence makes no sense?
