I am wondering whether Wikileaks cables that have been withheld so far may reveal that key US allies are horrified by Obama’s incompetence and waffling. US diplomats may have reported misgivings for example by Israel over lack of an Iran strategy and by Japan, Korea, Taiwan and Australia over China's failure to restrain North Korea and the weak US response, not to mention the Poles being exposed to Russian intimidation by removal of the missile shield to appease Putin (and the US left).
Assange could be manipulating US politics and Obama by withholding such cables and/or simply blackmailing Obama with threats to release the juicy ones.
Maybe there are cables involving diplomats reporting birth certificate or birth location witness blackmail attempts on Obama. There is a lot to play out yet with Wikileaks...
In a crazy world, your wikileaks theory sounds reasonable. Assange already called for Zero to resign. I’m sure there are more bombshells, used as insurance, to keep Assange out of jail.
