Rubio Warns Russia and China Are Already Moving in the Arctic

What is the Arctic, and why is Iceland strategically important to its defense?

The Arctic is Earth’s far-northern polar region, including the Arctic Ocean and surrounding lands. It matters strategically because military forces, submarines, shipping routes, and communications infrastructure increasingly operate there. Control and awareness in this region can affect both Europe and North America.

Iceland sits between those regions and near important North Atlantic approaches. Although it has no conventional military, it offers territory, infrastructure, technology, surveillance, and access for allied forces. More than 1,200 Americans joined allied forces in Northern Viking 2026, showing how Iceland supports defense without maintaining a large national army.

Russia’s military and covert activity, along with China’s growing Arctic ambitions, has increased attention to Iceland. NATO also worries about undersea cables, shipping lanes, and submarine activity. Rubio said Iceland’s strategic importance is growing, and future cooperation could expand surveillance and other security work.

What changes in US-Iceland security cooperation did Marco Rubio signal during his visit?

The main change is a possible expansion of practical security cooperation, not an immediate return to a permanent US base. Rubio said the world has changed and that the Arctic now demands greater attention. He also described Iceland as important to defending both Europe and the US homeland.

Washington could work with Icelandic authorities to improve surveillance, technology, infrastructure, and maritime domain awareness. Allied forces already use Iceland for exercises, maritime patrols, and rotational deployments. Northern Viking 2026 included more than 1,200 Americans alongside allied forces.

The United States ended its permanent Keflavik presence in 2006. Rubio did not say that a new base would be created. Instead, he expressed willingness to build on existing cooperation, especially after a new US-Danish-Greenland defense agreement. That approach could increase allied activity while preserving Iceland’s role as a cooperative host rather than a permanent US garrison.

How much allied military activity is already taking place around Iceland?

Allied military activity around Iceland is already substantial, even without a permanent US military presence. The country supports NATO through access, infrastructure, surveillance, and its strategic location. These contributions help monitor the North Atlantic and connect defenses for Europe and North America.

A clear example is Northern Viking 2026, which involved more than 1,200 Americans with allied forces in and around Iceland. The exercise was part of annual military cooperation. Other activity includes maritime patrols, exercises, and rotational deployments. These efforts provide training and improve coordination without requiring a permanent American base.

The article does not give a total number for all allied personnel, patrols, or deployments. It does show that cooperation is continuous and growing in importance. Rubio’s visit suggested that the United States and Iceland may expand this work, particularly in surveillance and maritime domain awareness, as Arctic and North Atlantic risks increase.

What kinds of military, covert, economic, and commercial activities by Russia and China are raising concern in the Arctic?

The article presents Russia as the more immediate and clearly documented security concern. Its activities include military capabilities, submarines, long-range strikes, gray-zone or covert warfare, and suspected intelligence activity. Russian threats also involve undersea cables, shipping lanes, and broader economic or commercial pressure with national-security effects.

One concrete example is a Russian spy ship reportedly seen around Iceland during the summer. Experts also described Russian submarine activity and gray-zone warfare as significant threats. These actions can gather information, test defenses, pressure governments, or endanger critical infrastructure without starting an open war.

China is described as having expanding Arctic ambitions and activities in the region. However, the article does not specify particular Chinese military or commercial operations in Iceland. An Icelandic security expert said China’s role is often exaggerated compared with Russia’s immediate military danger, especially on NATO’s eastern flank. The concern is therefore real but unevenly documented.

What could happen to NATO and North American security if undersea cables, shipping lanes, or submarine routes in the North Atlantic were disrupted?

Undersea cables, shipping lanes, and submarine routes form part of the North Atlantic’s security system. Cables carry vital communications and data. Shipping lanes support trade and military movement. Submarine routes affect surveillance and the ability to detect forces approaching Europe or North America.

If cables were cut or shipping routes disrupted, governments and businesses could lose communications, face delays, or pay higher costs. If hostile submarines moved undetected, NATO could have less warning and a harder time protecting reinforcement routes. These effects could weaken coordination between North America and Europe, even without a conventional attack.

The article says such threats have economic and commercial implications for national security. Experts also identify Russian submarines and gray-zone warfare as significant dangers. NATO’s response is increasing Arctic awareness, patrols, exercises, and surveillance. Stronger monitoring could expose interference earlier and help protect the infrastructure and routes on which allied defense depends.

How can the United States and its allies strengthen Arctic surveillance and defense without reopening a permanent US military base in Iceland?

The United States and its allies can strengthen Arctic defense through flexible cooperation rather than a permanent American garrison. This means improving surveillance, sharing intelligence, protecting infrastructure, and increasing coordination across the North Atlantic. It also lets Iceland contribute according to its capabilities, despite having no conventional military.

The article identifies several practical tools: exercises, maritime patrols, rotational deployments, infrastructure, technology, and domain awareness. Northern Viking 2026 demonstrated how allied forces can train together. NATO’s Arctic Sentry initiative and growing European capabilities offer additional ways to monitor the region. A US-Danish-Greenland defense agreement may also support wider coordination.

The United States ended its permanent Keflavik presence in 2006, and Rubio did not announce a new base. Future cooperation could therefore rely on temporary deployments and shared facilities. This model can increase presence when risks rise while avoiding the costs and political implications of maintaining a permanent US installation.

What is deterrence, and why do governments believe that demonstrating defensive strength can prevent war?

Deterrence is the effort to prevent an attack by showing that aggression would bring unacceptable costs. Governments seek it because preventing conflict is safer and less destructive than fighting after an attack begins. Deterrence can involve military strength, surveillance, alliances, preparedness, and a clear willingness to respond.

In Iceland’s case, exercises, patrols, infrastructure, and allied access demonstrate that NATO can monitor and defend the North Atlantic. Northern Viking 2026, which included more than 1,200 Americans, is one example. Such activity improves readiness and signals that Iceland and nearby routes are not undefended or ignored.

Rubio said history teaches that deterrence is the best prevention of violence and war. The approach does not guarantee peace, and the article does not claim that it eliminates every risk. However, continued allied cooperation could make covert operations, attacks on infrastructure, or military movements harder to conduct without detection or response.
