Obama and Petards

As a preface, I totally support Obama's decision regarding Bin Laden.  Obama is learning however that words have meaning.  If you recall Obama and his administration eliminated the words "War on Terror".  If there is no War, how do you justify killing Bin Laden as a combatant commander in the field?.  If the enhanced interrogation techniques were illegal as Holder claims, and since the intel that led to Bin Laden started with these interrogations, was not the action that derived from that information therefore also illegal (fruit from a poisoned tree).  Obama said that the days of the US acting unilaterally were over that we in essence would stop being a rogue (my words) nation.  Yet we acted unilaterally.  Europe is full voice decrying what we have done.  The words of candidate and President Obama have come back on him.  Hoist with his own petard.
