Our Common Wealth 670 is an organization committed to educating the public about the impacts of militarization throughout the Mariånas.

OUR MISSION

Our Common Wealth 670’s (OCW670) mission is to protect our ancestral lands, seas and skies from irreparable damage caused by military practices and other developments that pose a threat to our health, physical environment and livelihoods by increasing awareness of current military planning and the policies that effect us the most.

OUR VISION

We envision a healthier and safer environment for our community throughout the Mariana Islands.

OUR VALUES

We are a non-partisan alliance based in the Commonwealth of the Northern Mariana Islands (CNMI) under the Alternative Zero Coalition (AZC) umbrella, which includes the Tinian Women Association, Pagan Watch, and Guardians of Gani. We stand in solidarity with Prutehi Guåhan, Hita Litekyan, Mauna Kea Hui, and Marianas for Palestine.

Deep Sea Mining Toolkit

A critical decision is unfolding now in our islands’ waters and your voice is urgently needed.

This toolkit is your clear, accessible guide to understanding the federal push for deep-sea mining in CNMI waters—what’s at stake, why Indigenous communities are sounding the alarm, and how you can help shape the future of our ocean.

Inside, you’ll find step-by-step instructions for submitting comments, powerful talking points, and curated resources that unpack the environmental, cultural, and political impacts of mining the seafloor. Whether you’re new to the issue or already engaged, this toolkit empowers you to take informed action to protect our islands and the Blue Continent.

Frequently
Asked
Questions

What is militarization?

Militarization is a process by which a society organizes itself for military conflict and violence. It occurs when communities begin to privilege military goals, ideals and policies over those of the people. Some consequences of militarization include: increasing weapons development, defending national interests at all costs, base building, increasing troop size, etc.

Why do we stand for the “de-escalation of militarization” in the Marianas?

While OCW 670 recognizes the need to maintain security measures throughout the Pacific, we do not advocate for increasing militarization at the expense of people and environments. We seek to maintain the integrity of our Covenant negotiations in which the United States “will continue to recognize and respect the scarcity and special importance of land in the Northern Mariana Islands” (Article 8: Property, Section 806 in the CNMI Covenant).

How does militarization impact me in the CNMI?

We believe that increased militarization has unjustifiably resulted in the irreparable damage to our environments and our people’s health and well-being through destructive training and testing, including the use of violent weapons technologies like sonar. Left unchecked, militarization has the potential to cause further destruction throughout the Mariana Islands, eroding our ability to engage in proper self-governance. We also recognize that military policies are often enacted in our community in ways that are not in line with the health and sustainability of our people, such as when the U.S. military does not adequately comply with environmental regulations, promotes military goals at the expense of community health, ignores public input, and causes irreparable damage to the natural environment.

Why get involved?

As the descendants and rightful owners of this land, our active participation in the protection of our homelands is often in direct conflict with destructive military plans to use the Mariana Islands, including Pagan, for destructive training and testing. Therefore, your voice, input and knowledge as a protector of the Marianas is integral to the overall goals of OCW 670 and the broader Marianas community. With the support of our diverse community, OCW 670 can bolster its capacity to serve the needs of our islands’ people.

Who is eligible to join OCW 670?

Any person with a vested interest in the protection of the Marianas is encouraged to join OCW 670. We welcome individuals from all walks of life, from community members residing in the CNMI, to those living abroad; teachers, parents, children, man’amko, manhoben, artists, advocates and all others. OCW 670 does not discriminate on the basis of race, color, religion (creed), gender, gender expression, age, national origin (ancestry), disability, marital status, sexual orientation, or military status, in any of its activities or operations.

What is the level of involvement required to join OCW 670?

We encourage members to attend our re-occurring membership meetings to discuss recent events, community organizing and other important aspects related to OCW 670 goals. Our group depends on the knowledge, expertise and involvement of community members like yourself that allow us to maintain active and engaged conversations about important issues in our community. However, you are welcome to choose the level of involvement in the group that best suits your lifestyle.

Members are welcome to choose the level of involvement that works best for them. We encourage everyone to join our email list to receive monthly newsletter updates about the most urgent issues facing the Marianas, as well as notifications of upcoming OCW 670 events and educational opportunities. Those who want to play a more active role can join OCW 670’s Policy, Public Information, Logistics, Public Safety, and Environmental Health committees to get more involved in advocating for positive changes in our community.

What is expected of OCW 670 Members?

Please see our Code of Ethics regarding OCW 670’s expectations for group members. As always, we encourage respectful dialogue with one another and with others in the community, and actively seek to express our concerns as “one voice” to promote cohesiveness and professionalism when representing OCW 670.
