Mennonite Church USA - Peace & Justice Support Network
http://peace.mennolink.org/
The Peace & Justice Support Network represents the new and strengthened peace witness of Mennonite Church USA. We have combined the work of the Mennonite Church's Peace & Justice Committee and the General Conference Mennonite Church's Peace and Justice Resources (Commission on Home Ministries) into a single voice that speaks words of healing and hope and calls for organized response to the violence and brokenness in our world.

Center on Conscience & War (formerly the National Interreligious Service Board for Conscientious Objectors (NISBCO))
http://www.centeronconscience.org/
Not a very extensive website, but CCW/NISBCO is one of the primary advocacy organizations for conscientious objectors throughout the world. They do a lot of public education and outreach, trying to counter the aggressive military recruitment campaigns. They organize letter-writing campaigns for COs throughout the world. NISBCO also offers counseling and legal support for COs. While not religious in its focus or material, many of its staff come from pacifist religious traditions such as Quakers, etc. This group produces a good, though brief, quarterly newsletter. CCW/NISBCO also publishes the Draft Counselor's Manual, "the only comprehensive guide to the Selective Service System's draft regulations and manuals, including CO and other exemptions."

Central Committee for Conscientious Objectors (CCCO)
http://objector.org/
Some good, basic information on the site about thinking twice before enlistment, how to get out of the military if you've voluntarily enlisted, etc. Similar in many ways to NISBCO, though perhaps a bit feistier in their approach. They do a lot of educational outreach, provide counseling and advice to young people. An excellent resource for informational pamphlets and books, as well as a newsletter. One of the best listings of CO and GI rights links.

War Resisters League (WRL)
http://warresisters.org/
More of an activist orientation than NISBCO and CCCO, they organize protests and media campaigns against militarization and military recruitment, and organize war tax resistance. Several excellent links with other peace groups on the site. They publish an in-depth bi-monthly newsletter, posting most of its articles on-line, as well. The site contains quite a few downloadable flyers and information booklets.

National War Tax Resisters Coordinating Committee (NWTRCC)
http://www.nwtrcc.org/
Basically, a coalition of groups that work to support and inform people who feel they can't support the military actions of the US government through their tax dollars. NWTRCC publishes an thought-provoking newsletter, posting most of its articles on-line, as well. You can join their war tax resisters email discussion list. Lots of information and links on the site.

National Campaign for a Peace Tax Fund
http://www.peacetaxfund.org
Maybe less immediate for someone concerned about being drafted, but a necessary step for a more institutional recognition of legitimate conscientious objection within the country. Basically, this organization is pressing for national legislation that would allow COs to specify that none of their tax money can be used for military or violent purposes. Good info on the history of their efforts, some good links. Their newsletter is posted on-line.

Veterans For Peace
http://www.veteransforpeace.org/
VFP was founded by ex-service members “committed to sharing the horrors they experienced.”

The Israeli “Refuseniks”
http://www.seruv.org.il/english/default.asp/
This is a simple site put out by the Israeli “Refuseniks” – those Israeli soldiers who refuse to fight in the Occupied Territories. This is a courageous stance, since several have been thrown into jail for their beliefs. Most are not absolute pacifists. The group isn’t refusing military service or even questioning Israel’s policies of universal male conscription. They simply argue that Israeli military activities within the Occupied Territories are illegal and brutal and prevent the possibility of real peace in the region.

Christian Peacemaker Teams
http://cpt.org/
Christian Peacemaker Teams (CPT) is an organization committed to reducing violence by "Getting in the Way"–challenging systems of domination and exploitation as Jesus Christ did in the first century.

A project of the Mennonite Church USA, Mennonite Church Canada, Church of the Brethren and Friends United Meeting and other Christians, CPT has worked in Haiti, the Middle East, Bosnia, Chechnya,  Colombia, Mexico, Canada, and the USA. In all locations, CPT responds to invitations from grassroots movements seeking to rectify injustice in nonviolent ways.

We rely on the Biblical witness, the power of the Holy Spirit and the prayers of our church constituency to sustain us in the difficult work of making a just and lasting peace.

Conscience and Peace Tax International
http://www.cpti.ws/
Conscience and Peace Tax International aims to obtain recognition of the right to conscientious objection to paying for armaments and war preparation and war conduct through taxes. CPTI works through international movements and through international institutions such as the United Nations and the European Union.

Jewish Peace Fellowship
http://www.jewishpeacefellowship.org/
Jewish Peace Fellowship is a Jewish voice in the peace community and a peace voice in the Jewish community. We are a nondenominational Jewish organization committed to active nonviolence as a means of resolving conflict, drawing on Jewish  traditional sources within the Torah, the Talmud and contemporary peacemaking sages like Martin Buber, Judah Magnes and Abraham Joshua Heschel.

JPF was founded by in 1941 to support Jewish conscientious objectors to the military, to help educate local draft boards --accustomed only to the Christian roots of conscientious objection--of the theological basis of the Jewish position on conscientious objection, grounded in Torah, Talmud, and other sacred and religious texts.
