He was not addressing the legitimacy of the war itself (which has bipartisan approval).
He was addressing the method of conducting the war using drones (which you acknowledge began under Bush, but primarily criticise on a partisan basis as being an Obama failing).
If you consider the continuing use of drones as a partisan failing of President Obama, then it is fair to examine your recommended approach to war in partisan terms. Which is to make war more deadly for US soldiers. JayHawk has sustained his point, and you have tried to distract by changing the subject to the legitimacy of the war itself rather than your original critique about the techniques employed.
