Seems reasonable considering that Russia has absolutely no respect for European borders or laws. Why should they allow Russian assets to further damage Europe?

Seems reasonable considering that Russia has absolutely no respect for European borders or laws. Why should they allow Russian assets to further damage Europe? They are literally waging war against Europe, and it's not just limited to Ukraine. Russia has staged assassinations on European soil using radioactive and chemical weapons. They've sabotaged civilian and military infrastructure (both digitally and physically), plotted to bomb civilian cargo flights, etc. How much farther should Russia and it's agents be allowed to go before they're considered security risks?
