Former US ambassador to the UN John R. Bolton has a must read piece on Obama's incorrect analysis of history and how his foreign policy is dangerously naive.

This is my favorite part: "What is implicit in Obama's reference to "tiny" threats is that they are sufficiently insignificant that negotiations alone can resolve them. Indeed, he has gone even further, arguing that the lack of negotiations with Iran caused the threats: "And the fact that we have not talked to them means that they have been developing nuclear weapons, funding Hamas, funding Hezbollah."

This is perhaps the most breathtakingly naive statement of all, implying as it does that it is actually U.S. policy that motivates Iran rather than Iran's own perceived ambitions and interests. That would be news to the mullahs in Tehran, not to mention the leaders of Hamas and Hezbollah."
