Last night, Senator John McCain tried to lecture Barack Obama about Obama not knowing the difference between a tactic and a strategy.
Of course, McCain was wrong. The counterinsurgency methods introduced by general David Petraeus in Iraq were a tactical change, because they were a new means to achieve President Bush’s strategic end of a stable, unified Iraq.
A change in strategy might have been withdrawal or splitting the country into Kurd, Sunni and Shi'ite regions.
I hope the poor old fellow will make sure he's on more solid ground the next time he corrects a fellow senator in public.
