I didn't know which war was the first neither, but, yes, since the civilizations of Mesopotamia were the first know ones, it is indeed logical that the first wars happened there too.

The two nations are not at war at the moment, however it is possible.

I love your description of the peace from the past! 😊

I believe that the meaning of peace (between economically and culturally developed nations) has changed because they now all have devastating weapons, immense economic connections, as well as a huge potential war weariness for wars with similar/friendly nations.

Thus, I think that the war between U.S. and Germany is not unimaginable due to politicians or evolved human nature, but because of the pure interests of both countries. Which is logical when considered that the overall external politics are more and more lead by interests instead of tradition or emotions.
