Let's Make World War II the Last World War

The purpose of this book is to let the people--mostly the young people of today, who think they're living in hard times and that everything around them is so brutal and savage and of so much despair, though many think that way because of to the constant negative ambush they receive today from the media, schools, newspapers, and through many elites in our society who are taught that everything around them is going to hell in a handbasket--know that this is the best time in the world to be alive.
Most people are safer, better educated, and living around modern high-tech advances that make their lives easier. People have more wealth and leisure time than ever before. They are healthier and tend to live longer than ever before. The world is also more acceptable among the races and religions of the world, and this generation has the chance to live in everlasting peace without no World Wars, though there will always be conflicts among people and nations, and it will never be perfect.
This generation today must know that the world was a pretty savage doggy world throughout history, climaxed by World War II though savage wars did continue after World War II. They must also be taught that the perpetrators of the savagery were all people, races, and religions, not just some. For today's media want to use that narrative, and the victims of the savagery were also from all people, races, and religions.
We all know that slavery is wrong in America, but it ended over 160 years ago. Why not also talk about slavery before American slavery, like the slavery in Africa? And why not talk right now about slavery that's been going on right now in China, in North Africa by Isis, and in Libya? Because it doesn't get the media's narrative on who is good and who is bad. And one more thing about the media, how about talking about some of the good things that America has done throughout its history instead of bashing America all the time? For example, if America were to be wiped out by a tidal wave, the rest of the world would be in warfare because there will be no America to secure peace.
