THAT is why student activists have had to turn to other tactics to demonstrate our moral disapproval of Harvard's investment policy. For 15 years, activists have sponsored rallies, speeches and vigils; written letters; signed petitions; fasted; built shanties and sponsored a campus-wide referendum showing 65 percent of students in favor of divestment. All of these tactics have failed to make Harvard budge.

This leaves us with only one option--turn up the pressure. Students who want divestment must turn to activism that cannot be ignored by the Corporation. Of course, any tactics must be non-violent. But they should be disruptive. When petitions fail, sit-ins must take their place.

Militant tactics are the only way to achieve divestment. Years of dialogue and moderation have proved futile.

When Nelson Mandela was released from prison, he said, "We call on the international community to continue the campaign to isolate the apartheid regime...Now is the time to intensify the struggle on all fronts. To relax now would be a mistake which generations to come will not be able to forgive."

At Harvard, proponents of divestment have two options: support more decisive actions or give up the goal of complete divestment from South Africa.
