Once again, we utilize proper counterinsurgency. Additionally, the Laurentian majority "province" (even though Laurentia doesn't have provinces) doesn't revolt, due to the suppression of the Laurentian peoples. Additionally, the large "encirclement", which by far overextended, finds itself stretched incredibly thin before it even closes, and is quickly dismantled, because plains are no worse for guerilla warfare than any other place, due to either a lack of infrastructure for enemies to survive, or vast urban areas where guerillas thrive. Additionally, the revolts close to Alinya struggle due to overwhelming Laurentian populus there. Addressing political issues and putting the populus against these fighters for choosing violence over peaceful assembly (since violence, believe it or not, is bad), when violence is less useful than peaceful assembly for addressing political issues like socialism, since all citizens of Laurentia enjoy the rights to free speech and free assembly, which are valid political tools. This has resulted in support of the people, the lifeblood of a revolution, to fizzle away, literally just leaving the revolutionaries as pockets of conventional forces.
