I don't believe that a few Facebook posting on foreign policy issues by Sarah Palin are the sum of her knowledge on these subjects. Aside from that contention, the fact remains that all presidents surround themselves with foreign policy advisors, usually people who have spent the entire careers in this field and know what they're talking about. President Bush did this. His book about his presidency ('Decision Points') makes this unambiguously clear. It's axiomatic that a 'President Palin' would do likewise. I can easily see a John Bolton as a major source of foreign policy counsel for Palin.
I recall that during the 2000 presidential campaign a TV reporter, hostile to George W. Bush and eager to pin the 'dummy' label on him (even then) asked him if he knew the names of the president of one or two tiny, remote Third-world nations. Bush did not and the reporter smugly assumed that he had made his point. However, he was roundly criticized for playing a lame 'gotcha'! game and as we all know, Bush was elected, anyway. Just some food for thought.
Apparently I did not do a good enough job. I didn't mean to give any sympathy or consideration to the anti-Palin camp or to their positions. There is a difference between knowledge of foreign (or domestic) policy issues and knowledge of policy. My point is that she should study policy in general, both theory and applications, as a supplement to her knowledge of the issues; I did not intend to criticize her knowledge of specific policy issues. The far left treats policy as a fertile ground in which they can win through referendum, through legislation, through court order, through administrative rulings, and through innumerable other methods, where their goal is to wear us down or blindside us to get their way, and most on our side don't see the connections among those efforts or in many cases even notice the hidden policy agenda.
Sarah is now well read on the issues and well prepared for debate (she wasn't always that well prepared, but I still supported her in 2008 when I voted for the old RINO hoping to get her). I'm not concerned there. I want more though, since I believe she's as prepared in those areas as is useful. I want her prepared to govern and to take the fight to the far left when they shift their policy focus to another arena. She has to understand what they mean by "policy" and how to respond to policy manipulation beyond just making the executive branch do the right thing.
