Ramsey Clark, the former U.S. attorney general who went on to a career of far-left anti-American activism, is in Gaza this week to express his solidarity with the Hamas terrorists who rule the strip and opposition to any Israeli measure of self-defense against them. Normally when a Western pilgrim goes to Gaza to be manipulated by the Islamist regime there, we tend to think that it is the visitor who is discredited by his willingness to associate with an organization of ruthless killers. But perhaps in this case, it is Hamas that should be worried about being tainted by Clark’s friendship.

After all, though Clark was a civil-rights-enforcement lawyer in the Justice Department in the 1960s, his legal work since then has specialized not just in the defense of mass murderers but also in the support of them. While anyone, even killers, is entitled to a lawyer, Clark’s bizarre animus toward his own country has led him to be the mouthpiece for Saddam Hussein, Serbian strongman Slobodan Milosevic, Liberian warlord Charles Taylor, and Elizaphan Ntakirutimana, a leader of the Rwanda genocide. In these cases, Clark didn’t just seek to undermine the prosecution of the killers; he tried to rationalize their homicidal actions. Among the notably unsavory beneficiaries of Clark’s good offices were Nazi war criminals Karl Linnas, the commandant of the Tartu concentration camp in Estonia, and Jack Riemer, a Nazi concentration-camp guard. He also defended the Palestinian Liberation Organization against a lawsuit brought by the family of Leon Klinghoffer, the crippled American Jew who was murdered by terrorists on the Achille Lauro cruise ship.

While Hamas is always glad to welcome any Western fool who will pose for pictures with its leaders, perhaps in this case it is the Islamist group, which actively seeks to convey the false image that it is composed of victims rather than the killers they truly are, that ought to be worried by Clark’s embrace. Does Ismail Haniyeh, the Hamas political leader who welcomed Clark to Gaza, really want the world to associate him with the likes of Saddam, Milosevic, or Taylor, even if such comparisons are entirely appropriate? Then again, though the prospect that Hamas’s chiefs will be brought to the bar of justice for their numerous crimes seems remote at the moment, perhaps it is never too early for them to make sure that Clark is on call for the moment when he can add them to his roster of murderous clients.
