Conflict between Russia and Ukraine threatens Russia's relationship with the international community

The article I have linked discusses the recent downing of Malaysia Airlines Flight 17 by the pro-Russian rebels in Ukraine. The conflict in Russia and Ukraine has been going on for a while now, but this event is the first time the international community was greatly affected. This event also shows how reckless the Ukrainian rebels are and how dangerous it is for Russia to be providing powerful weapons for these people. If the rebels in Ukraine had no problem using their weapons to down a plane filled with innocent people, how can we know what else they might do? My questions for my classmates are “What will it take for Russia and Ukraine to end the violence and find a peaceful solution?” and “How can rest of the world assist Russia and Ukraine in ending their conflict?”
