Europe weighs solutions to curtail Russia’s growing hybrid warfare

Governments now moving faster to impose costs on Moscow for its increasing attacks over support for Ukraine

Russia’s suspected sabotage campaign across Europe appears to be gathering pace again, confronting governments with a problem they have struggled to solve since the start of the war in Ukraine: how to impose a meaningful cost on Moscow for attacks that remain deliberately below the threshold of conventional war.

Over the past month alone, an explosives-laden drone was discovered next to a Ukrainian cargo plane at Germany’s Leipzig airport, Poland has faced suspected acts of sabotage, and a string of unexplained explosions and fires have hit defence facilities supplying Ukraine across Europe.
