Since he did not demonstrate even a basic knowledge of the geopolitics of the 1980's it was a pretty safe bet he is/was either too young...or willingly ignorant.
I don't know how you got "...did not demonstrate even a basic knowledge of the geopolitics of the 1980's..." out of "...Bush Sr. led CIA felt when they were supplying Saddam with all of that support in their skirmish with Iran."
We all, or at least those of us who were around then, know that the USA was supplying arms to Iraq then. And we liked that idea, because of the way the Iranian students thumbed their noses at us for over a year. Clearly, Doug knew that little tidbit, too.
What is more of a stretch was for you to assume that he wasn't around yet just because he didn't know it was a very small fraction of the total weaponry that was being shipped to Iraq.
