Many of countries that have banned the use of their military forces using cluster munitions have their arsenals stocked with similar technology to deploy a large quantity of landmines over a large area via mortars or artillery. I find it extremely hypocritical. Eastern Ukraine is already now one of the most heavily mined areas of the world and will already take decades to demine.
