Since Bill Kristol and Joe Lieberman both believe in a policy of all-war, all-the-time and both seem to put more weight on warmongering than anything else in American politics, I wasn't surprised to see Kristol float a trial balloon suggesting Lieberman could be a good Republican vice presidential nominee.
Peter Wehner liking the idea seems a bit more surprising, since Lieberman's views on most everything else are well to the left of the GOP consensus and surely it's not hard to find Republicans with Lieberman-like levels of fanatical devotion to the killing of foreigners.
