The running joke about Obama defenders says that whenever Obama makes one his horrendous moves or continues yet another terrible policy started under George W. Bush, the defenders will claim that he is a master tactician, working many moves ahead of us, sometimes even in dimensions we can’t possibly perceive. With today’s decision by Obama to accept the resignation of General Stanley McChrystal and to ask General David Petraeus to step down one level to assume command of US forces in Afghanistan, Obama has made what I think finally is a good strategic decision on the political front.
