The equivalent here would be if that American judge was sanctioned by the EU for issuing the arrest warrant for Maduro. Or would be, if Venezuela was an ally of the EU.

That Maduro was a head of state and still subject to an extraordinary rendition means that now the EU has to worry about EU heads of state being violently extradited to the USA. Not because anyone in the EU cares about Maduro himself, but because the US has signalled by doing this that they don't care about the old rules.
