From Michael Mukasey WSJ 5/1/2012 "Arbraham Lincoln on the day following Robert E Lee's surrender delivered from the window of the White House mentioned NOT his achievments but instead looked forward to the difficulties of reconstruction and called for black sufferage, a call that would doom him as a memeber of that audience (John wilkes Booth) muttered he has just delievered his last speech." Lincoln took responsibility in August 1862 failures of General George McClellan , eventually sacked for incompetence and Secretary Edwin Stanton. Lincoln told a crowd that McClellan was not at fault for seeking more than Stanton could give and "I stand here,as justice requires me to do, to take upon myself what has been carged upon the Secretary of War."

Dwight Eisenhower penned a statement to be issued in anticipation of the failure of the Normandy invasion that read in part: "My decision to attack at this time and place was based on the best information available." "The troops, the air and the Navy did all that bravery and devotion to duty could do. If any blame attaches to the attempt it is mine alone."

A week later when it was apparent the invasion was an apparent success Eisenhower saluted the Allied Expedtionary Forces. One week ago..........
High was my preinvasion confidence in your courage , skill and effectiveness.....your accomplishments......have exceeded my brightest hopes. I truly congratulate you.........I am proud of you."

George W Bush also had occassin to announce a triumph of intelligence: the capture of Saddam Hussien. He called the success a tribute to the men and women now serving in Iraq. He attributed it to the superb work of the intelligenc community and to skill and bravery of our fighting force Like eiswenhower he lso mentioned himself Today, on behalf of the nation I thank the member of the Armed forces and I congratulate them

The intelligence community knew in early 2010 the location of bin Laden. Prior to issuing the order to strike in 2011 Obama made it clear that if the mission went wrong the fault would fall with Admiral McRaven who had the main decision making operational control of this mission."

What the bin Laden situation really delinates, to me, is the lack of presidential breeding. As the old saw goes you can't make a silk purse from a sow's ear.
I am not trying to be unkind here what some people see as arrogance or ego centric I view as attributed to the fact that Obama never had the long term opporutnity to become presidential. In the corporate world it is termed the "Peter Principle." It certainly explains Obama's continue use of "I" and "me"
