Two weeks ago I wrote in praise of not knowing what to think. Today I write in praise of knowing what to think and not acting on it, which is different. I write in praise of President Obama, in other words, or at least in dispraise of those who believe an opinion must be mother to a deed – the interventionists, the isolationists, the screaming chorus of the convinced whose contrary but equally belligerent voices might have driven a lesser man than Obama crazy.
