Russia, Ukraine the US and the European Union say all sides have agreed to steps to "de-escalate" the crisis in eastern Ukraine at talks in Geneva.
This is just step one. This basically just means that neither Russia nor the US and the EU is going to go into Ukraine to deal with the situation, and that the Russian government is calling the protestors in Eastern Ukraine to stand down.
The issue of Ukrainian reconiciliation and reunification, however, is going to be a separate issue. Kiev is very lucky that this didn't end up in civil war. One hopes that it stays this way. However, it's going to take a lot of effort on the part of the Ukrainians in the West to reconcile with the Russians in Crimea and the East. It's not enough to claim territory on a map if the people who live in that territory do not acknowledge or accept your presence in those territories.
It would be wise for Kiev to allow for Russian representation in the Parliament and in the Cabinet, provided that they come to Kiev to work. Allowing for a certain degree of autonomy may not be a bad thing for both sides. But if Ukraine wants to stay as one, it's ethnic majority population is going to have to embrace the ethnic minority as essential equals in the polity and in the society. Unfortunately, that's going to be a monumentous task, considering the animosity between the two sides that is just a flare up in a long history of animosity between Ukrainians and Russians. Above all, a common identity and history should be emphasized. Gestures need to be made, especially by the Ukrainains, even if they're only one way. Above all, the Kievan government needs to put the Russians in Ukraine and outside of Ukraine at ease while maintaining a positively effective grip on authority in Kiev as one country. Otherwise, the two will never grow back together well, just like a broken bone that is set improperly and heals incorrectly for the patient.
Think about it.
