This plan is a lot more simpler and it doesn't involve the cobalt pact causing conflict with eachother while still defending nations from the Kragg crusades. The line is much smaller and more effective and it'll work better for weaker nations like the Bastion Federation stay afloat without causing much conflict and it forces aggressors to act in a controlled environment helping Pilssussa combat the invasion
Also iron curtain is a much better name because it's a metal like cobalt and has a fun reference to irl history :)
