In my studies of history over the last decade, conducted on this blog, I’ve noticed that each generation has its own political thesis, its own dominant media, and its own dominant industry. Old theories, media and industries continue to exist, but they lose their importance as history marches forward, technology leading, economics following, media reflecting, and politicians trailing somewhere behind.
This is also true regarding our foreign relations. Each generation has a key ally and a key enemy. The identities of the friend and foe shift with the times. Germany, once a foe, has become a friend.
Saudi Arabia, once a friend, has become a foe.
