Can We Hope For Peace?

In our day we see a lot of fights and terrorist attacks happening throughout the world. Many people have different views on the situation. Some optimists think that there will be a time that ISIS will disappear and that we will have world peace. Other pessimists believe that we will be entering a new war, World War 3. I choose to go with the pessimists. I don't believe that ISIS will just give up or lie down after being reproached by the UN or Armies from the U.S. This is going to involve everyone. One thing we should avoid doing is discriminating. The U.S has said that it doesn't want to take in the refugees (mostly the Muslim ones) in fear that it would allow for them to commit terrorist attacks in their countries. This is an absolutely ridiculous notion that a group that is escaping war in their country would want to attack their own refugees just to get kicked out again. Having these ideas is dangerous because it really will start turning people (the refugees) against others.
 War at a grand scale is impossible to avoid and denying the existence of it is plain stupid. We already see that major countries are fighting back against terrorism but the fact that no one wants to admit that we are in the middle or at least the start of a new World War is ignorant or just plain naive. And as for those optimists out there, let's just say they have to much faith in the human kind to see the real horrors that are happening. There is no way of stopping it from happening but there are ways to make sure that it doesn't go nuclear. Like I mentioned before accepting the refugees would not only help them but would also make the country look well in their eyes. They (the countries) could also train the refugees to take back their homes and fight with the armies against the terrorist. All this and many more other things can be done to help reduce the effect of the World War. Remember at this point we can't stop it, but we can make sure less suffer from it.
