The backdrop: Two days after Theresa May laid out consequences for the attempted murder of one Russian defector, ex-spy Sergei Skripal, British police are treating another suspicious death as murder. Glushkov, whose cause of death was "compression to the neck," according to police, was a close friend of the late oligarch and well-known Putin foe Boris Berezovsky.
