The world as we've known it since 1945 exists because of American power -- economic, military, political and cultural.
Remove American power from the world order and it will quickly change into something much less friendly to us.
Beginning with this -- many of 195 mostly small but independent countries will be invaded and absorbed into their more powerful neighbors, until the map looks more like the empires of January 1914.
Empires, you may remember from history, are entirely self-justifying -- they don't need reasons or "moral authority" to invade their neighbors, because they exist to grow and expand.
Empires are deterred by strength, they are provoked by weakness, such as Hitler saw in the Rhineland, Austria, Czechoslovakia and Poland, and Vlad the Invader sees in Chechnya, in Georgia and now in Ukraine.
Destroying old empires was the single greatest accomplishment of the First World War.
Our inaction, allowing new ones to grow, would be the great disgrace of our time.
That power used to be a power for good. Not so much anymore.
Abject nonsense.
