Simply put: what purpose does NATO still serve? Should it be rolled up and packed away unless Putin has a Simpsonesque moment where he presses a button and Lenin climbs out of his case?
It still seems to serve as a stick for hawks in Washington to shake at the Kremlin, but why would France or Germany still help fund such an organisation? In the fight against terrorism, an alliance of police forces or intelligence organisations would be far more effective.
NATO membership hinders rather than helps EU autonomy, so what's the story?
