The picture

A unique hybrid: members pool trade, competition and much regulation in Brussels but keep defense and foreign policy largely national, often requiring unanimity. Combined GDP about $20 trillion, second only to the US. Strengths: market size, rule-setting power, trade deals and the euro. Weaknesses: slow growth, high energy costs, aging and fragmented defense. Ukraine's largest funder; most members are also in NATO. A trade truce with the US since July 2025 caps most tariffs at 15%. Investing: broad Europe or eurozone ETFs, and euro bonds.

Why it matters

The EU sets trade terms for a huge market and global rules on tech and climate, and is now trying to become a security power in its own right.

Key facts and numbers

EU treaties, Eurostat and IMF data, European Council conclusions and the published texts of trade agreements.

What to watch

Whether the EU can act fast without unanimity, absorb Ukraine and other candidates, and keep pace with US and Chinese technology.

▸Hungary long blocked Ukraine aid in European UnionFact

The relationship

Many EU foreign-policy decisions need unanimity, so Orbán's Hungary could stall them alone. It delayed the €50 billion Ukraine Facility, held up billions in military-aid reimbursements, threatened sanctions renewals and in early 2026 blocked the €90 billion loan over a Russian oil-pipeline dispute. Critics said he traded vetoes for frozen EU funds.

Since when and why

Brussels summits from 2022 to April 2026; the last veto, on the €90 billion loan and new sanctions, was lifted on April 22, 2026, after Orbán's defeat and repairs to the Druzhba pipeline.

How we know

Council records and summit conclusions document each block; workarounds such as opt-outs were designed explicitly to bypass Hungary.

What to watch

Disputed: Orbán said aid prolonged the war; opponents said he served Moscow. Magyar's government still refuses arms aid and delayed a step in Ukraine's accession talks.

▸European Union replaced much Russian gas with LNG in Energy: oil, gas and LNGFact

The relationship

In 2021 Russia supplied about 45% of EU gas imports. After the invasion and the 2022 Nord Stream pipeline sabotage, the EU cut that to roughly 13% by 2025, replacing it with Norwegian pipeline gas and LNG, mainly from the US and Qatar. It has agreed to end Russian gas imports entirely by late 2027.

Since when and why

The REPowerEU plan of May 2022; new LNG terminals in Germany and elsewhere; an EU law agreed in December 2025 bans Russian LNG from 2027 and pipeline gas by late 2027.

How we know

European Commission and Eurostat import data, the phase-out regulation, and LNG terminal records; trackers such as Bruegel's show the shift month by month.

What to watch

Whether swapping Russian dependence for US LNG creates a new vulnerability, given Trump's trade pressure, and whether landlocked Hungary and Slovakia fully comply.

▸Russian sabotage, drones and hybrid attacks on Europe targets European UnionWidely agreed

The relationship

EU states supplying Ukraine are the main targets: sabotage of rail lines, depots and cables, arson, cyberattacks and disinformation meant to raise the cost of support and divide voters. The EU has responded with sanctions on hybrid actors, drone-defense plans and tighter protection of undersea infrastructure.

Since when and why

Germany, Poland, the Baltic states, France, the Nordics and Romania, whose November 2024 presidential vote was annulled over alleged Russian interference; escalating through 2026.

How solid?

National intelligence and police findings, convictions of recruited saboteurs, EU sanctions listings for hybrid threats and NATO statements. Russia denies all of it.

What to watch

Debated: how centrally directed the campaign is versus opportunistic recruits, and what response would deter it without escalating.

▸Dollar dominance vs de-dollarization (yuan, gold, SWIFT rivals) faces a junior rival in the euro of European UnionWidely agreed

The relationship

The euro is the world's second reserve currency, about 20% of central-bank currency reserves against the dollar's roughly 57%. Since 2025 ECB President Christine Lagarde has called for a 'global euro moment' as US policy unsettled investors. But the euro lacks a single large safe-bond market and unified fiscal power behind it.

Since when and why

The euro launched in 1999; the ECB's June 2025 report noted that gold had overtaken the euro as the second-largest reserve asset at market prices.

How solid?

IMF COFER reserve data and the ECB's annual reports on the euro's international role measure the shares.

What to watch

Whether joint EU borrowing, such as the €90 billion Ukraine loan, grows into a true safe asset, and whether reserve managers shift toward euros or gold.

▸Emmanuel Macron champions 'strategic autonomy' for European UnionWidely agreed

The relationship

Since his 2017 Sorbonne speech, Macron has argued Europe must be able to defend itself and act without depending on the US or China: buy European weapons, build joint industry and, since 2026, lean partly on French nuclear forces. Once seen as anti-American, the idea gained ground after Trump's return.

Since when and why

Sorbonne speeches, September 2017 and April 2024 ('Europe could die'); his 2019 remark on NATO's 'brain death'; the Île Longue nuclear speech, March 2, 2026.

How solid?

His speeches are public, and EU programs such as SAFE, which favors European-made equipment, reflect the agenda.

What to watch

Eastern members fear it weakens US ties; whether Europe can really replace US intelligence, airlift and nuclear cover is debated.
