Ukraine's conflict flares up again in Feb. 2014 with the flow of Russian arms and fighters into eastern Ukraine. The U.S., Germany and France call on Russia to respect an agreement made in September 2014 to end the conflict. Russian president Putin's proposal is for a new agreement that takes into account the new territory captured by the separatists, in effect creating a new conflict zone with which to influence the government in Kiev. U.S. Secretary of State Kerry says the great technology available today makes it possible to see the flow of Russian forces and arms into eastern Ukraine, refuting Russia's claims that it is not involved. Germany's Merkel and France's Hollande plan to visit Russia to discuss the crisis with Putin as the Americans consider sending arms to the Poroshenko government in Kiev. In Brussels NATO chief Stoltenberg announces the preparations for the new Rapid Response Force to counter Russia's aggressive posture in Eastern Europe.
