WAR IN UKRAINEBreaking the Black Sea Blockade

There is an aspect to Ukraine war which has received insufficient attention, though it is now slowly coming into focus and where pressure could build for a NATO operation. This is the need to relieve the blockade Russia has successfully inflicted on Ukraine’s southern ports in the Black Sea. This is urgent not only because of the effect on Ukraine’s battered economy but also on supplies of essential agricultural products to the rest of the world.

From the start of this war there has been natural concern about the difficulties of keeping it confined to two belligerents within defined geographical boundaries. This concern is most often expressed in scenarios in which Vladimir Putin, having seen his ambitions thwarted and with his forces on the run, lashes out in anger, even with nuclear weapons.

While no one dares rules out an act of supreme irrationality from the Russian leader, as I have argued here and in the New Statesman, nuclear use would not solve any strategic problems for Russia, and would create many, many more. Nor has there been any indication that Putin is thinking on these lines: as yet he is not even prepared to escalate by acknowledging that he is actually fighting a war and not just a limited ‘special operation.’ Reservists have been signed up for the war in an almost covert fashion rather than through a full mobilization. Putin set a ‘red line’ at the start of hostilities, by demanding that NATO countries hold back from direct intervention in the war, and thus far this has been respected. For now NATO is making an impact simply by keeping Ukraine economically afloat and militarily buoyant.

There is, however, another aspect to this war which has received insufficient attention, though it is now slowly coming into focus and where pressure could build for a NATO operation. This is the need to relieve the blockade Russia has successfully inflicted on Ukraine’s southern ports in the Black Sea. This is urgent not only because of the effect on Ukraine’s battered economy but also on supplies of essential agricultural products to the rest of the world. If Russian forces continue to be pushed back, and as the diplomacy to bring the war to a conclusion is stepped up, this will be a critical issue to be addressed, possibly linked to Russian demands for relief from sanctions. If this is not addressed diplomatically then there could be demands on the major maritime powers to mount freedom of navigation operations to break the blockade.
