Lori Berenson, New York’s notorious revolutionary tourist, has finally been turned loose from a Peruvian prison after serving 15 years of a 20-year term for terrorist activities.

As a condition of her early release, the La Guardia HS grad and MIT dropout must remain in Peru until the end of her original sentence — although Peru’s Cabinet could commute the sentence and expel her.

For now, at least, she’s been hired as a translator for the Office of the Americas, a far-left outfit whose mission is working to “end the longstanding international culture of militarism” and confronting “areas of US foreign policy which its board of directors [including Ed Asner and Martin Sheen] consider illegal and/or immoral.”

Once a sandalista, always a sandalista.

It’s worth recalling Berenson’s story: She spent years traveling Central and South America as part of militant Marxist groups before hooking up with Peru’s Tupac Amaru — which killed some 50,000 Peruvians.

When arrested in 1995, she was living in a Tupac Amaru “safe house” — along with 8,000 rounds of ammo and 3,000 sticks of dynamite to be used in an attack on the Peruvian Congress.

Her original life sentence for involvement in terrorism was overturned after pressure from the Clinton administration. Convicted at a second trial, she drew a 20-year term.

The Berenson saga is a critical reminder that, even before 9/11, some nations took the threat of terrorism seriously and did something about it.

As a result, terrorism has all but been eradicated in Peru.

It’s to Peru’s credit that it never wavered from its determination to ensure that Lori Berenson paid a fair price for her deadly foolishness.
