News Releases

As this year’s NATO Summit approaches, key questions about the Russia-Ukraine war remain unresolved. Ceasefire talks have stalled, and the United States continues to struggle with how to compel Russia to negotiate. Without a clear and sustained U.S. commitment to Ukraine and European security, NATO’s credibility and future are at risk. Below, CFR experts and Foreign Affairs authors offer analysis and policy recommendations to help the United States and Europe confront those critical challenges. For more resources about Ukraine in particular, please visit CFR’s Special Initiative on Securing Ukraine’s Future.

Weathering the Storm: The Hague Summit and the Future of NATO

Fellow for Europe Liana Fix and Senior Fellow for U.S. Foreign Policy Rebecca Lissner argue that European leaders should avoid clashing with President Donald Trump at the NATO Summit in The Hague. In the coming months and years, the authors stress that the leaders should focus on increasing defense spending, further integrating Ukraine into the regional security architecture, and developing a European-led future for the alliance.

The World Needs a Stronger NATO

Secretary-General of NATO Mark Rutte writes that NATO needs “to become more lethal. That means strengthening our deterrence and defense posture and showing any aggressor that if an ally is attacked, NATO has the ability and resolve to hit back harder.” Read more in Foreign Affairs.

How to End the Russia-Ukraine War 

Distinguished Fellow Thomas Graham writes that ending the Russia-Ukraine war demands a shift in strategy from the Trump administration—one that compels Russian President Vladimir Putin to negotiate by coupling sustained pressure with pragmatic dialogue. A carefully crafted framework agreement, Graham argues, is the key to breaking the deadlock and advancing a durable peace.

Close NATO’s Door on Ukraine

Senior Fellow Charles A. Kupchan writes that NATO should “make clear that membership is not in Ukraine’s future. Closing the door on Ukraine will allow Kyiv and its supporters to get on with the task of making other plans for providing the country the security it needs and deserves.” Read more in Foreign Affairs.

The Limits of Putin’s Ambitions 

In his second brief, Graham argues that Putin’s war in Ukraine is not just about territory—it’s a calculated move rooted in history to reclaim Russia’s global influence and potentially redraw Europe’s borders. Graham notes that to safeguard European security, the West needs to revive its proven strategy: building a strong deterrent while pursuing dialogue to ensure long-term stability.

How to Make NATO More European

Jeremy Shapiro, European Council on Foreign Relations research director, writes that “the United States will not fill [NATO’s lead role] much longer. Europe now needs to lead the alliance, and to do that, a European needs to take the position of supreme allied commander.” Read more in Foreign Affairs.

The Senate’s New Ukraine Bill Will Not Work—But Here Is How to Fix It

George F. Kennan Senior Fellow for Russian and Eurasian Studies Stephen Sestanovich warns that the Sanctioning Russia Act would impose history’s highest tariffs and tank the global economy. As a result, he argues that Congress needs a better approach, one that strengthens existing sanctions and adds new measures the current bill ignores.

Read the policy brief for more on how to improve the Sanctioning Russia Act.

Reasons Why Trump Could Back Weapons for Ukraine

At a recent CFR event on the upcoming summit, Kupchan outlines three reasons why he believes Trump could increase military support to Ukraine—including growing frustration with Putin, cost-effective drone warfare, and a potential minerals-for-aid deal. Watch the video.

The policy briefs are part of the Ukraine Initiative and the Wachenheim Program on Peace and Security, which was made possible by the generous support of the Sue and Edgar Wachenheim Foundation.
