Less than 30 years after NATO bombs fell on Belgrade, Serbian troops are training alongside the same alliance on home soil. In May 2026, Serbia hosted its first ever joint military exercise with NATO, a two week drill that marks a dramatic shift in the country's relationship with the Western military bloc.
The drills took place in Serbia, a Balkan nation that has long balanced its military ties between the West, Russia, and China. For many Serbians, the sight of NATO flags next to Serbian ones on a training field carries deep emotional weight. The 1999 NATO bombing campaign, launched to stop a Serbian crackdown on ethnic Albanians in Kosovo, killed hundreds of civilians and remains a raw national memory.
A careful step toward the West
Serbia has maintained official military neutrality since 2007, but it has slowly increased cooperation with NATO through the Partnership for Peace program. This exercise, however, goes further than any previous collaboration. Serbian soldiers worked directly with NATO personnel in planned scenarios on Serbian territory. The government in Belgrade framed the drills as a routine training event, not a shift in foreign policy. But the symbolism was hard to ignore.
Why locals paid close attention
For ordinary Serbians, the exercise stirred old debates. Some see closer ties with NATO as a path to European Union membership and economic stability. Others view any cooperation with the alliance as a betrayal of those killed in 1999. Protests broke out in several cities ahead of the drills, organized by nationalist groups and veterans' associations. The government responded by emphasizing that the exercise was limited in scope and did not compromise Serbia's neutral status.
The drills also drew attention from Serbia's traditional allies. Russia, which has close cultural and political ties with Serbia, expressed concern. China, another key partner, watched quietly. Both nations have courted Serbia with investments and diplomatic support, especially as the West has sought to pull the country closer.
A nation navigating between worlds
Serbia's position at the crossroads of Europe and the Balkans has always forced it to juggle competing loyalties. The NATO exercise does not mean Serbia is joining the alliance. But it does signal that Belgrade is willing to open a new chapter, however cautiously. For a country where the memory of war is still alive, hosting the former enemy for joint training is a step that would have seemed unthinkable just a decade ago.
