Some background on North for context.
Oliver North ran an illegal covert operation to buy arms from Iran ('83-'88) to support the Nicaraguan Contras with the full cooperation of the administration at the time (Reagan). He lead a group that circumvented the Boland Amendment that forbade US activities to overthrow the Nicaraguan government.
"Freedom Fighters", as coined by Reagan, were the ousted right-wing military leaders trying to resume power from Daniel Ortega (we called him Communist to make it sound good). Drugs were never brought into Congressional testimony even though there was evidence to show it was used to purchase arms from neighboring countries.
Maybe this is why North has a hard on for Kerry:

You don't think North is just a regular vet do you?
