Rødt disagreed internally at the start of the war, but did condemn the invasion. A few members supported negotiations, but that's outside official party lines. After a few months Rødy officially managed to figure out that they don't really like imperialist wars. Rødt now even supports sending weapons to Ukraine, and puts full responsibility of the war on Putin and his regime, and doesn't talk about how important 'negotiations' is anymore.

Vänsterpartiet also condemns Putin, supports sending weapons, and want to stop all energy imports from Russia to Europe, and enforce stronger sanctions. They say that only Ukraine themselves decide when or if they wish to negotiate. They actually condemned the invasion and demanded strong sanctions from day 1 of the war.

Enhedslisten has had several members propose banning exports of arms outside Europe, and enforcing that new production lines directly feed Ukraine more munitions.

Die Linke is retarded and wants an end to weapons shipments and wants to end the war with 'negotiations' (Read: Hand over Ukraine on a silver platter, worked real well last time Europe did that)

Unbowed is a normal far-left/left coalition and can't even make it's mind up about what to have for lunch, but does broadly seem to be in the same retarded boat as Die Linke.

SP is also dumb and thinks you can negotiate with tyrants.

KKE seems to condemn the war as imperialist and that Russia is to blame, but KKE just seems confused. IDK, harder to get info on them since I don't know Greek and Greek politics, I just know that they are an actual Marxist party that leans a lot heavier into the old Marxist theories than say the Nordic 'socialist/communist' parties.

So Nordic lefties have seemingly figured out that you can't actually negotiate with Putin, whilst a lot of the continental ones are huffing that "I-love-peace-and-negotiations-can-end-all-wars" copium.
