The release of 92,000 classified documents related to the Afghanistan war has prompted many comparisons to the Pentagon Papers. But that's a bit superficial, writes Richard Tofel for ProPublica. "In terms of important disclosures, it's not even close."

There's really no comparison to the Pentagon Papers bombshell, which exposed decades of lies and dissembling on Vietnam by presidents from Harry Truman to Lyndon Johnson. Hopefully, the presidential reaction to the leak will constitute another difference, Tofel writes.
