Sentiments of nationalism are rising in America and it now seems to be cool again for young people to be pro-American. This is a bit surprising to see in a place like Los Angeles, and from what I can see on my Facebook feed it is stronger in more rural places.
It seems to be a global phenomenon that nationalism is rising strongly in other countries. Britain voted to exit the UK, Trump (an extreme nationalist) won the Republican nomination, and many other countries are showing stirrings of nationalism.
Nationalism is very dangerous as it also rose in the run-ups to major wars like WW1 and WW2. Life globally is much better when people can appreciate that folks in other countries are human beings with family, friends, and lives just like their own.
Why is nationalism rising? I think Islamic terrorism globally is working. It is putting fear into many countries. However, I think the result of that fear will not be to allow Islamic countries like ISIS or Saudi Arabia or Iran to grow and be left alone. I think it will cause military buildup and a growing anger in superpower countries that could lead to a global war to exterminate Islam. Trump and other extreme nationalist leaders seem to advocate this approach.
