Rather interesting article in the Washington Post. Ukraine seems to be continuing the ground offensive.

Government troops were engaged in a pitched battle with rebels on Saturday just outside the separatist bastion of Donetsk and plan to advance next into the city that has been at the heart of the pro-Russian insurgency.

If the army succeeds in retaking Horlivka, a city of almost 300,000 people where fighting was fierce Saturday, they will be within a few miles of Donetsk. Rebels have held sway there since the spring, ruling what they call the Donetsk People’s Republic. Cars created roadblocks out of town Saturday, and the railway station was packed with people desperate to board the next train out.
It is looking increasenly likely that the Ukraine will succeed unless Russia directly intervenes on the ground. If they do, Europe and the United States is almost certain to respond with economic sanction that will cripple the Russian economy. The current outline of sanctions outlined after the Malaysian airlines flight would be vastly expanded. One would also think aid in weapons and training would be on the table. If Russia doesn't directly intervene, what is to stop the Ukraine from turing their attention to Crimea next?
