Peter Wehner reviews Senator Biden's flawed policy positions and concludes (my emphases):
On many of the most important and controversial issues of the last four decades, Mr. Biden has built a record based on bad assumptions, misguided analyses and flawed judgments. If he had his way, America would be significantly weaker, allies under siege would routinely be cut loose, and the enemies of the U.S. would be stronger.
There are few members of Congress whose record on national security matters can be judged, with the benefit of hindsight, to be as consistently bad as Joseph Biden's. It's true that Sarah Palin has precious little experience in national security affairs. But in this instance, no record beats a manifestly bad one.
