I am developer from Lviv, Ukraine. I already prepared molotov cocktails. Ukraine is united as never before. Lot of people donate big amounts of money, buy necessary goods for army, everyone is very supportive, everyone knows what to do. There is no single pro-russian people there. Every citizen will fight for our land, because truth is on our side, and it become obvious to the whole world.
