Blackmail is certainly a possibility. But it could cut either way. For example, Israel could blackmail him into being less pro-arab. (I’m assuming the Mossad is up to the task of finding his real birth certificate)
I don’t see what he’s doing now as being the result of blackmail. In his books - esp. “Dream From My Father” he comes across as a smug, leftwing, America - hating internationalist. That’s pretty much how he’s governing.
If he suddenly starts acting against type, that would be evidence that blackmail is being done, IMO.
Determining where the BC is located isn’t the problem, really. It’s getting someone in the position to do so more motivated to reveal it than to conceal it.
You mean acting conservative and patriotic?
That would mean that loyal conservative Americans were blackmailing him.
You’re either funnin’ or something else....
