Summary
Poroshenko is a hypocrite and a scumbag. He waged a nonexistent war in which people died. […] It is a civil conflict, not a war against Russia.
Disproof
Recurring pro-Kremlin disinformation narrative about the war in Ukraine. The war in eastern Ukraine is not a civil conflict, but a well-documented act of aggression by the Russian armed forces, ongoing since February 2014. See similar narratives about Ukraine's role in the conflict and the Minsk Agreements here.
