Are you going to cause World War III?

I was just watching “Battleground” (1949). The first movie to be made about the Battle of the Bulge. In part of it they had pastor talking to the troops and he asked the question was it necessary for them to be there. He said that when ever someone with the believe of a super-race or a super-believe threaten the rest of society then yes it was necessary.
Now we have ISIS. Men who act exactly like the followers of Hitler if not worse. It is something that needs to be stopped before it causes 13 million to die horrible deaths in concentration camps in addition to 22 to 25 million military death. It is said that nearly 80 million dies in total in World War II.

In that time many saw how Germany changed, and they tried again and again to talk the Germans into not pursing what they ended up doing. Now we have an identical if not worse threat to the freedom of the world before us.
Today though we live in different world. A world that easier to travel within and also more dangerous. More dangerous due to weapons that can be made these days. Weapons we are allowing people to make that would willingly and gladly use upon us due to their super-believe that only they are the children of God when in reality their very actions and behavior say the opposite.
