Amusing how some attempt to hang everything on "oil." Libya is too small potatoes, to use an old expression, with only 2 percent of reserves at best, and of some importance to Europe, but whose output is easily replaced by other sources (as is happening).
Same with Iraq, whose oil goes mostly to European and Asian markets, and means little to American and UK economies (whose governments started the mess because they thought it would be easy and would bolster their popularity.
