The incident comes just days after the Czech president, Petr Pavel, has urged Nato to “show its teeth” in response to Russia’s repeated testing of the alliance’s resolve on its eastern flank, suggesting a range of options including switching off its internet, cutting off its banks from global financial systems and shooting down jets that violate allied airspace.
