Even though this isn't a shooting war for the EU, there are certain steps that might seem contradictory to the liberal principles that we normally claim to adhere to. Russia has been declared an enemy, even if that exact term might not have been used.

In a conflict enemy propaganda will be shut down, and enemy assets will be targeted. This means severe economic sanctions, blocking RT/Sputnik, and arming the Ukrainian armed forces to the teeth.

With luck, the Ukrainians will be able to end this without the situation getting out of hand. If not, this might escalate and get real ugly real fast.
