The question becomes, was Pollard really worth it? I know the Israelis wanted him back, but for Bibi to take one for the team for Pollard? I’m not saying “no” but did they really want him that bad, or was Pollard a gift, just clear out cell space for republicans.
If one wants to play armchair psychologist, it is far more interesting to delve into the motivations of Barack Obama and ponder whether he hates Israel or the United States the more. Clearly, he is no friend of Israel, why then would he release its spy? A plausible answer is that he hates America the more and he despises its very existence so there is in his world no such thing as treason against an illegitimate and repressive land.
More likely Obama concluded that he undermines both the legitimacy of the United States by releasing a spy after having released murderous Islamists and he undermines the relationship between the United States and Israel by releasing an Israeli spy and generating a backlash. One can also not discount the possibility that Obama is cynically attempting to restore his relationship with the American Jewish community which is so rich with Donors
It is not likely that deals concerning the very existence of Israel living under missile range of Iran equipped with nuclear bombs would turn on the fate of Pollard.
