MC, we Americans like killing.  So many of us stand behind cold blooded murder of those we do not like.  I wish we could develop enough empathy to sense the loss on the killing of anyone.  I think that among developed countries, we stand out as uniquely willing to kill whether our own citizens or innocents as collateral damage in drone strikes or other war type scenarios.  It does not have to be this way.  BTW, I thought in sum Nixon was a good President.  Also Obama brags about killing because Americans like to hear about the latest killing done in their name.
