In the modern world wars still exist and many countries use them to achieve different goals. In my opinion wars are always wrong for a number of reasons.
     The first and most important reason is wars are inhuman and barbarian. Only narrow-minded people solve their disagreement in this way. It is often suggested that wars cause death of millions. Let's remember The Second World War and how much suffering, bloodshed and brutality it brought to the world.
    One final argument against wars is that wars are very dangerous for the environment, because the nuclear bomb can ruin our nature and bring irreparable harm to our health.
     To sum up, I think wars are always wrong and I hope people will solve their disagreements by way of compromise and a peace treaty.
