Russia has not started the war in Ukraine, however, there is no other solution for a conflict in Donbas except for a military answer.
No evidence given. Military operations in Eastern Ukraine were launched in 2014 by an armed group under the command of Igor Girkin (nickname - "Strelkov"), Russian citizens and an agent of the secret service of the Russian army. That time, almost all the "leaders" and the commanders of the armed groups of the separatist "republics" in Donbas were also citizens of Russia that since the spring of 2014 has been massively supplying them with heavy weapons, ammunition, vehicles and fuel.
