Apropos nothing, it is interesting from a general historical standpoint to look at the consequences of "regime change" to the success of any nation's prosecution of a war. Certainly in the U.S., regime change has almost invariably culminated in a death knell for any war effort (FDR doesn't really count, as his VP succeeded to the POTUS, and the US army was within 50 miles of Berlin when FDR suffered his fatal stroke). But, e.g., Johnson to Nixon, and then Bush to Obama, produced a nightmarish drag on war efforts.
