The United States released a new National Security Strategy in December 2025. It put an “America First” frame on foreign policy. It also used very tough words about Europe.
The plan did not end U.S. ties with Europe or NATO. It did change the tone. It told Europe to do more for its own defense. It also attacked some European rules and political choices.
What the strategy does
A National Security Strategy is a broad policy plan. It shows how a White House sees the world. It covers threats, allies, trade, war, and U.S. goals. It does not create a law by itself.
The 2025 National Security Strategy says the United States should put its own safety and strength first. It gives the Western Hemisphere a bigger role. It calls for firm action on migration, drug gangs, foreign power, energy, and trade.
Europe gets some of the plan’s hardest words. The paper warns of decline and what it calls “civilizational erasure.” It points to migration, low birth rates, rules, and limits on speech.
Still, the paper says Europe matters to the United States. It says the U.S. needs a strong Europe. It also says no rival power should control Europe.
Why Europe became a main target
For many years, U.S. policy treated Europe as a close partner. NATO was built around shared defense. Russia, and before it the Soviet Union, was the main military threat in Europe.
The 2025 plan does not erase that past. But it puts much more focus on Europe’s own politics. It says the United States should help Europe change course. It also says Washington should work with European groups that share more of its views.
That is a big change in tone. The plan spends less time on what Russia may do. It spends more time on what the White House says Europe is doing to itself.
Russia, Ukraine, and peace talks
The paper also uses softer words about Russia than many older U.S. plans. It calls for a fast end to the war in Ukraine. It also calls for more stable ties with Moscow.
That does not mean Russia stopped being a threat. The war was still going in 2026. European states still saw Russia as a major risk. NATO members kept adding arms and raising defense spending.
Our guide to the Zelensky peace plan shows how talks changed from late 2025 into 2026. Our report on U.S. and European sanctions on Russia shows how pressure on Moscow changed too.
The new plan says Europe should carry more of the cost of its own defense. That may cut the U.S. load. It can also make allies wonder how much help they would get in a crisis.
What it means for NATO
The paper still says NATO has value. It also praises allies that spend more on defense. But it asks if some European states will stay strong U.S. partners if their politics and people change.
That caused alarm in Europe. NATO runs on trust as well as weapons. If allies doubt each other, joint plans get harder.
Europe has tried to build more military strength of its own. That work started before the paper came out. The new U.S. tone gave it more speed.
The war in Ukraine still shapes this debate. Our report on the Chernobyl radiation shield shows how the war still affects safety and policy in Europe.
Why the Western Hemisphere gets more focus
The plan gives the Western Hemisphere a much bigger role than many recent U.S. plans did. It ties this idea to the Monroe Doctrine.
The goal is easy to see. The White House wants the United States to stay the top power in its own region. That includes migration, drugs, trade, ports, energy, and foreign money.
This does not mean Europe or Asia no longer matter. It means Washington wants to put more time and power closer to home.

China is still a major rival
China still gets a lot of focus. The paper talks about trade, tech, supply chains, Taiwan, military power, and jobs.
The White House wants the United States to stay ahead in key fields. It also wants less risky reliance on China. At the same time, it wants U.S. allies in Asia to do more for their own defense.
The idea is simple. The plan asks what best serves U.S. power, wealth, and safety.
Why this matters at home
Foreign policy can feel far away. But it can reach daily life fast. Trade rules can change prices. War can change fuel and food costs. Defense plans can affect jobs and taxes.
A simple world map can help readers follow the places in the plan. A NATO guide can also help explain how the alliance works.
The bigger question is how the United States now sees an ally. The 2025 plan says allies still matter. But it also asks them to spend more and carry more of their own load.
What changed by 2026
By September 2026, NATO was still active. Europe was still working with the United States. U.S. and European leaders were still trying to shape the war in Ukraine.
But the ties were rougher. European leaders spoke more about relying less on Washington. Defense plans in Europe got more urgent. Fights over Russia, Greenland, trade, and politics put more strain on the old bond.
The best way to read the 2025 National Security Strategy is not as a breakup note. It is a new deal. The United States still wants allies. But it wants them to do more, pay more, and fit more closely with an “America First” view of the world.
