There are plenty of shallow analyses of ISIS and Europe's travails therewith, Robert Kagan's article for The Wall Street Journal isn't one of them. It isn't short and it isn't upbeat, but it does take a dispassionate view of the mess and its many antecedents.
I believe if you read it you will learn, or at least be reminded of, some aspects of the situation you weren't considering. Kagan may be this generation's Henry Kissinger, high praise indeed at COTTonLINE.
