All I see in those articles are the familiar themes of oil, self-interest and the distorting effect of a UN veto.
Words are cheap but I'm not aware of any mandate for the EU to take proper action against Russia- or against any other nation that mounts a disproportionate military action against a non-EU state on spurious grounds.
The UN could be an excellent vehicle for this purpose but if the culprits have a veto right or buddies willing to exercise one for them, what hope is there? as I said, it's like allowing your car to run out of gas then buying a motorbike because the car is absolutely useless. If people don't want to use their car they could at least be honest about it.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
