Germanyhas this week deployed a permanent military brigadebeyond its bordersfor the first time since the end of World War II. The historic unit dispatched to thecapital of Lithuania, Vilnius,was inaugurated Thursday byGerman Chancellor Friedrich Merz, who said during a military ceremony in the city that "the security of ourBaltic alliesis also our security." The groundbreaking German military decision is perhaps the most significant in a steady stream of moves by European nations to bolster defenses onNATO's eastern flankamid persistent security threats from Russia andPresident Donald Trump's insistencethat Europe does more both to defend itself and pay for that defense. It also comes despitepersistent efforts by the Trump administrationto bring to anend the Kremlin's three-year-long war in Ukraine. Among Ukraine'sEuropean allies, the three Baltic nations of Lithuania, Estonia and Latvia — linked to NATO's main territory only by a narrow corridor that stretches between Russia and its staunch ally Belarus known asthe Suwalki Gap— are perhaps themost vulnerableto an expanded Russian assault. On Thursday, Merz said that "Russia's aggressive revisionism" since itsinvasion of Ukrainein 2022 meant it could seek to redraw the broader map of Europe and not just that of Ukraine. Standing alongside Merz, Lithuanian President Gitanas Nausėda added thatRussia and Belarushad already begun conducting military exercises on his country's border. The new German brigade on NATO's eastern flank will comprise a heavy combat unit of some 4,800 soldiers, hundreds of civilian staff, and 2,000 vehicles, including tanks. It will be headquartered in Rudninkai near Vilnius and is expected to be fully operational by the end of 2027. "Anyone who threatens an ally must know that the entire alliance will jointly defend every inch of NATO territory," Merz said. Trump has been putting pressure on America's NATO allies to increase their military spending, previously accusing Germany and other European countries of "freeloading" at Washington's expense and even going as far as implementing a temporary pause onmilitary aid to Ukraine in March this year. It also marks ashift away from America's guarantee of European securityagainst Russia that has been in place since World War II which has yielded U.S. hard and soft power throughout the continent and beyond. After his center-rightChristian Democratic Union party won the German election in February, Merz said his "absolute priority" was "strengthening Europe as quickly as possible so that, step by step, we can really achieve independence from the U.S." In line with Germany, other European front-line countries have begun upping spending in order to fortify their borders against Russia and Belarus. Earlier this month, Lithuania announced it would spend around $1.2 billion on its military, raising it to 6% of its annual gross domestic product. Neighboring Poland, meanwhile, recently allocated an additional $2.6 billion to the sector, raising it to 4.7% of its GDP this year. Despite American diplomats holding several rounds of bilateral negotiations with diplomats from Russia and Ukraine — Trump held anas-yet-fruitless phone conversationMonday with Russian President Vladimir Putin — the U.S. president has expressed frustration with his Russian counterpart continuing to launch missile and drone attacks on Ukrainian civilians while negotiations to end the fighting are ongoing. Meanwhile, Putin said in a video conference with Russian government officials Thursday that his military had begun creating a "security buffer zone" along its border with Ukraine, a day after he visited the western Russian region of Kursk that Russia says itsforces reclaimed from Ukraineearlier this month. Putin's latest move comes after Russian negotiators reportedly threatened during direct negotiations last week to seize the Ukrainian cities of Kharkiv and Sumy if Ukraine did not agree to the Kremlin's demands that essentially amount to a surrender from Kyiv. The Institute for the Study of War, a Washington-based think tank, this week described the threat as a warning sign from Russia ina report. "This tactic suggests that Russia will make additional, more extreme territorial demands during war termination talks should Ukraine agree to Russia's ceasefire preconditions," it stated.
