Obama Slips Up Over Auschwitz

Hillary Clinton suffered irreparable damage to her reputation with her remembrance of landing in Bosnia under sniper fire only for a TV clip to turn up showing her stepping off the plane smiling and shaking hands with the natives. She claimed to have been tired and had misspoken.
Fast forward a few months and hey looks it Obama in New Mexico, let's listen into what he has to say.
"I had a uncle who was one of the, who was part of the first American troops to go into Auschwitz and liberate the concentration camps."
And so up went the chorus of "hang about son" from everyone with even the most basic knowledge of history.
There could be several reasons for such a painfully embarrassing slip up. Obamas uncle could have been part of Stalin's Red Army who did actually liberate the prisoners from Auschwitz or we can take his campaign runners explanation that he actually meant to say Buchenwald, Obama just confused the names of the concentration camps. Fair enough, could happen i guess but it is only just this side of credible to confuse the two, especially as Auschwitz is easily the most infamous concentration camp.
It does seem a theme that American and British accounts of the second world war routinely write the Soviets out of the story and cast the US and UK as the heroes, thus creating the false impression among the general public that Germany was defeated by the US and Great Britain.
Whatever the reason behind Obamas slip, whether it was a lie, confusion or ignorance, he cannot afford to be so careless with his speeches again and stay credible.
