NATO is engaging with the United States to gain clarity on Washington’s decision to withdraw approximately 5,000 troops from Germany, as tensions within transatlantic relations intensify amid ongoing conflicts in the Middle East. The Pentagon announced the troop reduction on Friday, stating that the move would be completed within six to twelve months following a review of U.S. force posture in Europe and assessments of operational requirements on the ground.

As of the end of 2025, around 36,436 active-duty U.S. military personnel were stationed in Germany, significantly more than the 12,662 troops in Italy and 3,814 in Spain. German Defence Minister Boris Pistorius indicated on Saturday that the reduction was anticipated, both across Europe and in Germany specifically. NATO spokeswoman Allison Hart emphasized that the development highlights the importance of European nations increasing their defense investments and assuming greater responsibility for collective security.

The announcement follows heightened friction between U.S. President Donald Trump and German Chancellor Friedrich Merz. Merz had criticized the United States’ position in Middle East negotiations, accusing Iran of humiliating Washington at the negotiating table. Trump responded by disputing Merz’s comments and simultaneously announced plans to impose a 25 percent tariff on cars and trucks imported from the European Union, citing non-compliance with a trade agreement reached the previous summer.

Trump has repeatedly threatened to reduce U.S. troop presence in Germany and other European countries during his tenure, advocating for Europeans to bear more of the burden for their defense. The current troop withdrawal appears linked to dissatisfaction with European allies' lack of support for U.S. efforts in the Middle East war and their unwillingness to contribute to peacekeeping operations in the strategically vital Strait of Hormuz, which Tehran’s forces have effectively sealed off.

In addition to military adjustments, Trump accused German automakers Mercedes-Benz and BMW of exploiting American consumers, reinforcing his rationale for the forthcoming tariffs. The German automotive industry, a major exporter within the EU, warned of potentially severe consequences from the tariff hike. Hildegard Mueller, head of Germany’s automotive lobby group VDA, called for urgent negotiations to de-escalate the situation.

Earlier, Trump suggested the possibility of withdrawing U.S. troops from Italy and Spain, countries he criticized for their opposition to the Middle East conflict. “Italy has not been of any help to us and Spain has been horrible, absolutely horrible,” Trump said, implying those withdrawals could be imminent.

German Foreign Minister Johann Wadephul, speaking from Morocco, stated that Germany was prepared for a reduction in U.S. troop numbers and was addressing the issue within NATO in a spirit of trust. However, Wadephul stressed that key U.S. military installations in Germany, such as Ramstein Air Base, remain indispensable for both countries.

The European Union reaffirmed the importance of the U.S. military presence, describing Washington as a vital partner in maintaining Europe’s security and defense architecture. NATO continues to engage with the U.S. to better understand the scope and impact of the troop redeployment on the alliance's collective capability.
