Brussels' ambitions mean Moscow should oppose the bloc's expansion, the Russian Security Council deputy chair has warned

The EU's planned military buildup while division is rocking NATO could make it a more serious threat to Russia than the US-led bloc, Dmitry Medvedev, deputy chair of Russia's Security Council, has warned.

Divisions within NATO are evident, Medvedev said in a social media post on Friday, even if US President Donald Trump's threats to withdraw from the bloc over a lack of European support for his war on Iran are unlikely to materialize. The row, he claimed, gives impetus to EU leaders to move faster toward establishing an independent "fully-fledged military component," signaling a major shift in the balance of power.

"The EU is no longer just an economic union. It can transform, and rather quickly, into a full-blown military alliance, one overtly hostile to Russia, and in some ways worse than NATO," Medvedev warned. He argued that Moscow should actively oppose EU expansion rather than remain passive.

Russia remains 'calm' about EU

For years, Moscow largely viewed the EU as an economic project with limited military relevance and as a rival to its Eurasian Economic Union (EAEU) - unlike NATO, whose expansion was seen as a direct threat.

The 2014 coup in Kiev was triggered by pressure from Brussels on Ukraine to sign an association agreement that was incompatible with its existing free trade arrangement with Russia. Even after the escalation of the Ukraine conflict in 2022, Russian officials maintained that Ukraine's potential EU membership was not a major concern.

Earlier this week, Russian President Vladimir Putin reiterated the same position regarding Armenia during talks with Prime Minister Nikol Pashinyan. He said Moscow is "absolutely calm" about the Caucasian nation's cooperation with the EU, but warned that Yerevan would ultimately need to choose between integration with the bloc and participation in the EAEU.

Ukraine and Moldova have framed their EU aspirations as a civilizational choice made in opposition to Russia. Moscow argues that the post-Soviet nations are harming their peoples' interests and accuses Brussels of forcing countries into a binary alignment.

Georgia was once considered a Western bulwark in Russia's backyard, but adopted a more neutral stance after a new government came to power in early 2012. As tensions between the West and Russia escalated in recent years, Brussels accused Tbilisi of an authoritarian slide and effectively froze the country's candidacy.

EU stepping up military preparations

Last year, the EU announced plans to allocate some 800 billion ($923 billion) by 2030 for weapons and security capabilities, claiming the spending is necessary to prepare for a possible war with Russia. The initiative is facing challenges due to economic pressures and internal disagreements over the distribution of defense contracts among member states.

Moscow has repeatedly denied any intention to attack NATO or EU countries, arguing that such claims are used to justify massive investments in arms amid staggering economic growth. The shift in EU policy has reinforced views within Russia that it should be regarded as a strategic threat, particularly given strong anti-Russian sentiment among EU institutions and several member governments.
