Enough is enough. It's time to let Jonathan Pollard go. The former naval analyst sentenced to life in prison in 1987 for spying for Israel has done his time. His continued incarceration serves no purpose.

Once rightly reviled in the Jewish community for a crime that many worried would unleash unwarranted suspicion of dual loyalty, Pollard has since garnered widespread sympathy for what can certainly be seen as an overly harsh punishment.

The campaign to grant him clemency has intensified recently, with Israeli Prime Minister Benjamin Netanyahu writing to President Barack Obama to seek official clemency. Even former Secretary of State Henry Kissinger has added his voice to the chorus of former U.S. officials and members of Congress pleading Pollard's case.

For humanitarian reasons, not to mention reasons of fairness - he was duped into pleading guilty with the promise of a lenient sentence - Obama should heed these requests. At a time of general nervousness over the administration's positions on a host of political and diplomatic issues, it would be a well-receivéd gesture. Not to mention the right thing to do.
