Aside from the word “started” both are obviously true. We certainly did not start the war in Ukraine, but we are for sure using it to fight a proxy war.
It is fascinating that Zelenskyy has become the sole major voice of Ukraine to the west. Clearly Ukrainians hate Russians and many will die fighting to avoid the kind of oppression and genocide that would happen if Russia took control, but the idea that there is zero dissent and nobody just wants to surrender to stop the casualties does not pass the sniff test. Feels very political like the propaganda wars of the first and second world wars.
