Ukraine war: does Europe need a new direction?

Europe can and must respond, La Stampa insists:

“Most of the Russian diesel is loaded there [at Primorsk] and must be transported via the Baltic Sea, passing a number of EU countries in most of which these tankers are now subject to sanctions. EU countries and the UK have been tightening controls for a year now and could expand these measures further by seizing shadow fleet vessels that are subject to sanctions, and, for those not under sanctions, looking for other grounds to intervene.”
