Europe Faces Security and Stability Challenges in US President Trump's Second Term

Trump's calls for increased defense spending are causing political and social tensions across Europe. His recent push for NATO members to contribute five percent of their Gross Domestic Product (GDP) has triggered debates over national budgets and priorities. Increased military expenditures could require governments to reduce healthcare, education, and infrastructure funding or resort to higher taxes and increased borrowing, placing economic burdens on citizens and businesses. These measures may, in turn, exacerbate a perceived cost-of-living crisis, fuel anti-NATO protests, and increase support for fringe or pro-Russian parties, complicating Europe’s security landscape at a time of rising geopolitical threats. 

Beyond military concerns, Trump's second term will likely increase economic pressure on Europe. At the 2025 World Economic Forum in Davos, Switzerland, he linked security commitments to trade disputes, criticizing European nations for alleged unfair trade practices. His threats to impose tariffs on European goods in response to EU regulatory actions, including enforcement of the Digital Markets Act against US tech giants like Apple, Google, and Meta, have heightened tensions. European governments now face the challenge of balancing regulatory priorities with maintaining a stable transatlantic relationship, as economic disputes become more intertwined with security considerations. 

Trump's leadership has also coincided with the rise of hybrid threats and covert influence operations, including cyberattacks and disinformation campaigns targeting European institutions, elections, and events such as the Paris 2024 Olympics. Russia, Iran, and Azerbaijan have exploited this permissive environment to expand their influence and launch sabotage campaigns across Europe. Concerns over diminished US commitment to NATO are prompting many European nations to reevaluate security strategies, boost defense investments, and enhance capabilities to counter hybrid threats. Hostile actors may escalate efforts to exploit divisions within NATO and the broader transatlantic alliance.

Greenland has emerged as another strategic concern under Trump's second term. Situated between the US and Russia, it is critical for missile defense, trade routes, and access to key resources such as oil, gas, and rare earth minerals. Trump has applied economic pressure on Denmark, threatening tariffs if it refuses to sell Greenland to the US. Although Danish officials insist that their recent USD 2 billion increase in Arctic defense spending was part of long-standing plans rather than a direct response to Trump's pressure tactics, the combination of this aggressive posture and growing influence from Russia and China will likely prompt Denmark to further prioritize Greenland's defense. 

Trump's approach to the Ukraine conflict is also testing NATO's unity. By appointing retired General Keith Kellogg as special envoy and aiming to secure a ceasefire within 100 days, his administration seeks a rapid resolution. However, if the terms favor Moscow, NATO's credibility could suffer, emboldening Russia and raising doubts about US commitment to European security. European leaders may need to prepare for a scenario in which the US prioritizes short-term stability over long-term deterrence, possibly forcing them to take greater responsibility for regional defense.

As Trump's second term unfolds, Europe faces crucial decisions about its security and strategic direction. NATO cohesion, economic balance, and resilience against hybrid threats will be key to maintaining regional stability. How European nations respond to these challenges will shape the future of transatlantic relations and determine Europe's role in an evolving global order.
