The head of the alliance's military committee says member states are studying "proactive" actions against Moscow

NATO members should find ways to be more aggressive towards Russia, the US-led alliance's top military chief has said.

Admiral Giuseppe Cavo Dragone, chair of the NATO Military Committee, told the Financial Times (FT) in an interview published on Sunday that member states have been weighing options to respond to what he described as Russia's "hybrid war."

"We are studying everything ... being more aggressive or being proactive instead of reactive is something that we are thinking about," Dragone said.

The commander added that a "pre-emptive strike" could be considered a "defensive action," though it would be "further away from our normal way of thinking and behavior."

According to FT, diplomats from Eastern Europe have been especially vocal in demanding tougher actions against Russia, including retaliatory cyberattacks. Dragone noted, however, that NATO's decision-making has been constrained by legal and ethical concerns, as well as jurisdiction.

In September, NATO increased air patrols in Eastern Europe and the Baltic states in response to alleged airspace violations by Russia. Moscow has denied claims that its aircraft and drones encroached on NATO airspace and accused the allies of warmongering.

Politico Europe reported last week that NATO was also considering joint offensive cyber operations against Moscow. Russia has denied hacking Western institutions, insisting that it has instead been the target of numerous cyberattacks, including some claimed by pro-Ukrainian groups.

Russian Ambassador to Belgium Denis Gonchar said last week that NATO members were pursuing a "rampant militarization" of Europe under the guise of deterring Russia's "non-existent" plans to attack them.
