Trump made the remarks in a social media post after Merz said earlier this week that the United States was being “humiliated” by Iran’s leadership and questioned Washington’s strategy in the conflict, which has entered its third month and has disrupted global energy flows.

“The United States is studying and reviewing the possible reduction of Troops in Germany, with a determination to be made over the next short period of time,” Trump wrote.The threat marked the latest strain in relations between Washington and Berlin as Trump has repeatedly criticized NATO allies for refusing to support the U.S. military campaign against Iran, while European leaders have raised concerns over the economic consequences of prolonged instability in the Gulf.

Merz said on Wednesday that his personal relationship with Trump remained “as good as ever,” but added that he had “had doubts from the very beginning about what was started there with the war in Iran.”Speaking hours before Trump’s post, Merz said Germany and Europe were facing significant economic pressure from the closure of the Strait of Hormuz, the vital shipping route through which around one-fifth of global oil supply had moved before the conflict began on Feb. 28.

“We are suffering considerably in Germany and in Europe from the consequences of, for example, the closure of the Strait of Hormuz,” Merz said. “And in that regard, I urge that this conflict be resolved.”The waterway has remained effectively shut since hostilities intensified, adding to volatility in global energy markets and raising fears of wider supply disruptions across Europe and Asia.

Merz, who met Trump at the White House in March shortly after the U.S. and Israel launched bombardments against Iran, had then said Germany was prepared to work with Washington on a strategy for a post-conflict regional order if Iran’s current government were to fall.

He also warned that an extended war could inflict serious damage on the global economy.

Trump, however, has openly attacked the German chancellor in recent days. On Tuesday, he said Merz wrongly believed Iran should be allowed to possess a nuclear weapon and wrote that the German leader “doesn’t know what he’s talking about.”

“It’s no surprise that Germany is doing so poorly, both economically and in other respects,” Trump added.The dispute has revived memories of Trump’s first term, when he sought to withdraw about 9,500 of the roughly 34,500 U.S. troops then stationed in Germany, arguing Berlin was failing to spend enough on defense. That plan was announced in 2020 but never implemented, and former President Joe Biden formally halted it after taking office in 2021.

Germany hosts several major U.S. military installations, including the headquarters of U.S. European Command and U.S. Africa Command, Ramstein Air Base, and Landstuhl Regional Medical Center, the largest American military hospital outside the United States.

Merz said his government remained “on good speaking terms” with the Trump administration despite the latest dispute.

Prime Minister Inga Ruginiene announced new measures to safeguard the nation’s borders following repeated airspace incursions involving smuggler balloons entering from Belarus.

The government’s response highlights Lithuania’s proactive and responsible approach toward national defense and its dedication to upholding international aviation standards.

Speaking at a press conference in Vilnius, Prime Minister Ruginiene explained that Lithuania will begin to intercept and neutralize unauthorized aerial objects that pose risks to air traffic and public safety.

The decision follows multiple incidents in which unidentified balloons crossed Lithuanian airspace, temporarily disrupting flights at Vilnius Airport.

The prime minister described the move as essential to maintaining the integrity of national borders and protecting the lives of civilians.

She emphasized that these steps are part of Lithuania’s broader commitment to ensuring regional stability and cooperation within the European Union and NATO frameworks.

Ruginiene noted that Lithuania remains open to dialogue and collaboration with neighboring countries to prevent such incidents and strengthen mutual trust.

The government’s focus, she added, is on deterrence through readiness, coordination, and peaceful engagement, ensuring that Lithuania’s actions remain consistent with international law and European values.

The prime minister also addressed the temporary closure of several Belarus border crossings, explaining that these were necessary precautionary steps taken to secure national interests and minimize disruption.

Travel by diplomats and European Union citizens leaving Belarus continues to be allowed, ensuring that humanitarian and diplomatic mobility remains unaffected.

Ruginiene described the situation as a reminder of the importance of unity among European allies in facing modern challenges that often blend technology, security, and politics.

In recent weeks, airspace safety has become a key topic across Europe, with several countries reporting disruptions caused by drones and other unidentified aerial objects.

Lithuania’s firm yet measured response has been welcomed by regional observers as an example of responsible governance and decisive leadership.

It reflects the country’s ability to act quickly while maintaining transparency and adherence to international norms.

Foreign Minister Kestutis Budrys echoed the prime minister’s sentiment, calling for a collective European response to strengthen regional airspace monitoring and improve coordination between NATO allies.

He stressed that recent incidents should not be viewed as isolated occurrences but as challenges that require strategic cooperation and preparedness.

According to Budrys, these coordinated efforts are vital in preventing destabilizing activities that could affect peace and stability across the continent.

Lithuania’s defense authorities have also confirmed that they are in close communication with NATO partners to share intelligence and coordinate airspace protection.

The possibility of invoking NATO’s Article 4—calling for consultations among member states when security is threatened—was mentioned as part of the government’s comprehensive approach to maintaining vigilance and unity.

Experts view Lithuania’s actions as a demonstration of resilience and responsible statecraft in a region that continues to navigate complex geopolitical dynamics.

The government’s decision to enhance monitoring systems and adopt preventive measures reflects its forward-looking strategy, balancing defense with diplomacy.

Prime Minister Ruginiene reaffirmed Lithuania’s unwavering commitment to peace and cooperation, stating that the country seeks stability through strength and partnership.

She called on neighboring nations to respect international borders and work together to promote safety, trust, and peaceful coexistence.

By prioritizing airspace security and transparency, Lithuania is setting a positive example for regional collaboration.

Its swift, clear, and measured response underlines the nation’s role as a responsible member of the European and transatlantic community—dedicated to protecting its people, preserving peace, and ensuring that the skies above Europe remain safe and open for all.
