As Sec Gen, he can openly bash the demean the US without fear of anyone at the UN objecting.
Obama can skin and grin or shuck and jive his way through anything. The President presents himself as a buffoon President Obama is a front for a power grab. Take this person seriously. The President presents himself as a non-threatening person but he has evil intentions. The Trilateral Commission and the Council on Foreign relations are behind Obama. I believe Obama acts for the CFR and Trilateral Commission. With the help of these powerful allies Obama is capable of merging the US Presidency with the UN Secretary General.
