Zelenskyy has abided by every U.S. led ceasefire agreement. Russia has refused to abide by the ceasefire agreements and is now hitting civilians directly and intentionally.
Zelenskyy is intentionally stalling the peace talks. I got attacked for saying this but it is the truth. The war needs to end. The opportunity for Ukrainians is significant and the US has offered a great thing to Ukrainians. It is a shame this is happening.
