The temporary truce in Ukraine will soon be over and the Ukrainian army will then try to squash the insurgency by all possible means. It is unlikely to achieve that.
Today the coup president signed an EU association agreement in Brussels. The preferred trade status with Russia will thereby be over and the Ukraine will fall into a deep depression. Its industry is not competitive against western European ones and it can not be sustained without the Russian markets. The most knowledgeable engineers and workers, especially from the big weapon producers, will move to Russia and leave the Ukrainian industry to rot.
As Mark Adomanis correctly remarks:
The association agreement has always been seen in highly politicized and symbolic terms as a “civilizational choice” in which Ukraine would be able to leave behind its dark, eastern past and march forward into the safety and comfort of the European Union. This was a huge mistake. In reality the association agreement has nothing to do with culture or history and is much more basic: a highly technocratic bit of economic liberalization. There is no “European” way to end gas subsidies, and no “civilized” way to cut pensions. These steps are either taken or they are avoided. Since economic liberalization is not very popular in Ukraine, since Ukrainians continues to express extremely left-wing economic views, the struggle to implement free trade is likely to be long and nasty.
The agreement will still have to be signed off, and then implemented, by a new Ukrainian parliament. I seriously doubt that will happen.
Meanwhile the fighting in the east will continue and, when the coming push by the army fails as it is likely to do, will see further steps towards more independence for the eastern regions.
