Eh, i dont know the point of your comment, but just to clarify, Podemos is not a communist party, altough it is supported by some communists / has some communist in the party. Sumar as a whole is even less to the left than they are, despite having also some parties inside the group that could be considered communists.
Its not true that Podemos is against anything that helps Ukraine, they are all in for a cease fire and for an end to the war through dialogue which should be done from the EU mainly, the same way they are in for a cease fire/end of the war in Gaza, what they are against is spending billions of euros that are needed here to send weapons and war vehicles to Ukraine, the same way they do not support sending weapons and war vehicles to palestine nor no one expects that to be the position of any party here.
