Imagine a peace march where the Berrigan brothers didn't get arrested, or Joan Baez didn't sing, or Daniel Ellsberg didn't speak.

Imagine a war where Ron Kovic didn't protest, Martin Sheen didn't march, Elizabeth McAlister didn't pray.Here's a look at where some of the nation's best-known peace activists are now. Not surprisingly, some are back in the streets, back on television and, maybe soon, back in jail.

- Father Daniel Berrigan, who along with his brother Philip founded Clergymen and Laymen Against the War in Vietnam and who was arrested many times during the '60s and '70s, now works with churches in New York City to create sanctuaries for soldiers.

At 69, he lives in a Jesuit community in lower Manhattan, is a frequent guest lecturer at colleges around the country, and ministers to AIDS patients.

Already arrested several times for protesting the gulf war by throwing his own blood on buildings and blocking streets with mock coffins, Berrigan is slated to appear in court at least three times in March and April.

It is, he said, "like old home week, to be involved in this work again. Some of these friendships had lapsed over the years, and it's wonderful to be with them now."

- Philip Berrigan, 67, a former Jesuit priest, and his wife, Elizabeth McAlister, 51, a former nun, were both in the forefront of the peace movement during the Vietnam War and served many months in prison for their actions.

Now both must appear in court several times in the next few weeks in the Washington area on charges stemming from sit-ins and protests that defaced property at the White House and Pentagon with blood and oil.

Their daughter, Frida, 16, and son Jerry, 15, also have been involved in altercations with police over the gulf war. The family is part of a communal living arrangement at Jonah House in Baltimore, and McAlister and Berrigan support their family as contract house painters.

"We have been part of every major demonstration because we cannot not be counted," McAlister said. "We feel this need, as do thousands of others around the country who are acting locally."

- Daniel Ellsberg leaked the Pentagon Papers to The New York Times and became one of the most outspoken opponents of the Vietnam War. For the past 20 years, he has continued to oppose the "Star Wars" program and protest American military actions, such as the invasions of Grenada and Panama.

Now living in Berkeley, Calif., he is a senior research associate for the Center for Psychological Studies in the Nuclear Age, a research arm of Cambridge Hospital at Harvard University.

The day the ground war began, the 59-year-old Ellsberg was arrested in front of the White House during a silent vigil for peace.

"I'm a Jew born and raised a Christian, and in my 20s, 30s, and 40s I would have said I had no religion, but I did," Ellsberg said. "I acquired a religion, and its preachers were Martin Luther King, Gandhi and Rosa Parks, and one of the things they have taught me is not just that you pray, but where you pray. I would have felt ashamed if I'd kept silent and out of sight like a lot of other people who are keeping their heads down."

- Tom Hayden was a member of the Chicago Seven. He married Jane Fonda and they made a lot of money and became "angels" to various liberal political causes.

Today, Hayden, 51, is a Democratic state lawmaker from Santa Monica who chairs the California Assembly's committee on higher education, and also serves on the natural resources and banking committees.

Now split from his famous actress wife, Hayden declined comment on the war.

Fonda - "Hanoi Jane" to millions of critics who were outraged when she went to North Vietnam during the war - is now engaged to communications mogul Ted Turner, whose Cable News Network has seen dramatically increased viewership during the war. She has not spoken out about the war.

"It's a different kind of war," Fonda publicist Pat Newcomb said in January.

"She, like everybody else, is watching television every night and praying that it will be over very soon with minimum loss of life," Newcomb said.
