NATO and America: From Trump to Now (2017–2025
This article explains the complete history of NATO and America from Donald Trump’s first presidency in 2017 till now in 2025. It covers Trump’s tough stance on defense spending, Biden’s cooperative approach, NATO’s response to Russia’s war in Ukraine, and the future outlook after Trump’s return. Written in simple English, it helps readers worldwide understand why NATO and America sometimes clash, how Europe is preparing for self-defense, and what the future of NATO may look like.
2017 – Trump Becomes Presiden
Trump called NATO “obsolete” because he felt other countries were not spending enough on defense.
Later, he said NATO was “no longer obsolete” after meeting NATO leaders.
But trust was already shaken.
2017 Brussels Summit
Trump pushed allies to spend 2% of their GDP on defense.
He did not clearly confirm America’s promise to defend allies (Article 5).
This made Europe worried about U.S. commitment.
2018 – More Fights
Trump attacked Germany for buying gas from Russia (Nord Stream pipeline).
He met Putin in Helsinki and seemed to believe him more than U.S. intelligence about election interference.
NATO countries became nervous, thinking Trump was too friendly with Russia.
At the same time, the U.S. sent more troops and weapons to Europe (so in action, America still supported NATO).
2019 – INF Treaty
America left the INF Treaty (nuclear missile agreement) because Russia broke the rules.
NATO mostly agreed with this decision.
2020–2021 – End of Trump’s First Term
Trump still demanded more money from NATO allies.
Europe started making its own defense plans, in case America became unreliable.
Ukraine added NATO membership into its constitution in 2019.
2022 – Russia Invades Ukraine
NATO became stronger again.
NATO sent troops and weapons to protect eastern Europe.
Ukraine was not a NATO member, but NATO gave big support.
2025 – Trump Returns
Trump won again and came back as president.
At the 2025 NATO Summit in The Hague, countries agreed to spend 5% of GDP on defense by 2035. Trump called this a “historic win.”
But Trump also said America’s promise to defend NATO members “depends on your definition,” which scared Europe.
He welcomed Poland’s president and promised U.S. troops would stay there.
At the same time, a new Pentagon plan focused more on defending America and less on fighting Russia/China worldwide.
Simple Summary
Trump years: Lots of fighting words, but America still helped NATO with troops and money.
Europe: Felt America was unreliable, so they started spending more and planning for themselves.
Russia’s war: Made NATO stronger and more united.
Now (2025): NATO is richer and stronger, but still worried if Trump really supports them in a crisis.

Trump vs Biden: NATO Policies (2017–2025)
Topic Donald Trump Joe Biden
View of NATO Called NATO “obsolete”, often questioned its value. Said NATO is “essential”, always confirmed U.S. commitment.
Defense Spending Pressured allies to spend more; threatened U.S. exit if they didn’t. Encouraged allies politely, but strongly supported burden-sharing.
Article 5 (Mutual Defense) Sometimes refused to clearly confirm; in 2025 said “depends on your definition.” Clearly promised that U.S. will defend allies every time.
Relations with Russia Spoke warmly about Putin, doubted U.S. intelligence; worried allies. Called Putin a threat, united NATO against Russia after 2022 invasion.
Military Support to Europe Sent troops and weapons, supported Eastern Europe, but with harsh words. Expanded U.S. troops in Europe, reassured allies with calm diplomacy.
Trade with Europe Started trade wars (tariffs on steel/aluminum). Tried to repair trade relations, worked on cooperation.
Big NATO Summits 2017 & 2018 Brussels: Criticized Germany, demanded 2%. 2025 Hague: 5% deal but doubts on Article 5. 2021 Brussels: Strong unity after Trump. 2022 & 2023: Focus on Ukraine war support.
Style of Leadership Transactional, confrontational, “America First.” Cooperative, diplomatic, “Allies First.”
Simple Summary
Trump: Tough talk, pressured allies, sometimes scared them, but still gave troops and money.
Biden: Friendly approach, rebuilt trust, made NATO stronger especially after Russia invaded Ukraine.
NATO’s Future After 2025 (Trump’s Return)
- Defense Spending Will Go Higher
NATO countries already agreed to 5% of GDP defense spending by 2035.
Trump will keep pushing hard, maybe even faster, so Europe spends more and U.S. spends less.
- Doubts on Article 5 (Mutual Defense)
Trump said America’s commitment “depends on your definition.”
Some allies fear: If Russia attacks, will America really come to save us?
This doubt may make Europe prepare for self-defense without U.S..
- Europe May Become More Independent
France, Germany, and others may build stronger European Union defense systems.
Europe could reduce dependence on America step by step.
- Ukraine’s Future Still Unclear
NATO supports Ukraine, but Trump is not as supportive as Biden.
He may push for peace talks with Russia, even if Ukraine loses land.
This may cause divisions inside NATO.
- U.S. Global Focus May Change
A new Pentagon strategy (2025) says focus is on homeland defense and the Americas.
This means less focus on China and Russia overseas, more on U.S. borders and nearby regions.
- Risk of NATO Weakening
If America pulls back and Europe doesn’t fully unite, NATO could become weaker.
But if Europe steps up and spends more, NATO could become more balanced (not just U.S.-led).
Simple Summary
Trump back = More money demands + Less U.S. guarantee.
Europe = Needs to be ready for self-defense.
Ukraine = Big test for NATO unity.
Future = NATO may be stronger with more spending, or weaker if trust breaks.
