David Cameron must have actually lost his mind. In the middle of all the sanctions, he just loaned one of the Elgin Marbles to Russia, further infuriating Greece (from whom they were originally, famously stolen) after Greece loyally backed up the rest of the European Union (and NATO) on anti-Russia policies this year.
It’s one thing to petulantly insist on keeping the British Museum’s stolen artifacts from the Parthenon. It’s quite another to loan them out to an active enemy country in a taunt to one’s ally.
