"The Influence Of Its Signatories"

I can't quite remember what it is, but I think the NYT is leaving something out here...anyone want to help?

The substance of the letter is less notable for what it says — the positions were frequent talking points for the Obama administration before it faced the inevitable compromises involved in negotiations — than for the influence of its signatories.

Among them is Dennis B. Ross, a longtime Middle East negotiator who oversaw Iran policy at the White House during the first Obama term; David H. Petraeus, the former C.I.A. director who oversaw covert operations against Iran until he resigned two years ago; and Robert Einhorn, a longtime State Department proliferation expert who helped devise and enforce the sanctions against Iran.
