Apparently, notwithstanding Secretary of State Kerry's warnings to Russia to behave, the arms still flow into eastern Ukraine:
“We know that they sent, for example, last week a column of over 100 vehicles which included tanks, artillery, multiple launch rocket systems,” Army Col. Steve Warren said, adding that these actions are consistent with Moscow’s behavior in eastern Ukraine for several months.
Like I said, a ceasefire as we bizarrely call for in the aftermath of the MH17 shoot down can only allow Russia to do more of this. The proper response is to help the Ukrainians defeat the pro-Russian forces and regain control of the east.
