1.Both South and North belonged to americans - one nation.Russians get excint,and even if they still existed,they never were ukrainians.So,first mistake - we do not have one nation here.
2.European powers could beat USA in 1860 - but they do not cared,so they do not supported South.USA could beat soviets now,but,after kgb started war AFTER they made deal with USA that they do not start war,they care.
Deep state would not ley soviets win - but,they also do not let Ukraine win.That is why USA do not send tanks and planes,but ald IFV and ammo.
I undarstandt,that ,average bulgarians need to belive on long dead Mother Russia - but,average poles need to belive in just USA ally.If i could stop beliving in fairy tales,you could do the same.
