For the second time in one week, Russia has violated the air space of a NATO member. On Sunday, a Russian drone flew through Romanian airspace, coming just days after a Russian drone incursion over Poland. Both incidents represent an unprecedented provocation between Vladimir Putin and NATO with the potential to cast the West into armed and prolonged conflict. There is no playbook for theatrics such as these; Putin’s antics — although momentarily contained — reveal an official disregard for sovereignty and statecraft without clearly-defined objectives, ambitions or outcomes.
