The author, Robb, wrote a book entitled, Brave New War: The Next Stage of Terrorism and the End of Globalization (2007). I have not read the book, but the intro says: "the technology that has enabled globalization also allows terrorists, criminals, and violent ideologues of every stripe to join forces against a far bigger and richer foe without revealing their identities, following orders, or even working toward the same ultimate goal. This new brand of open-source warfare enables insurgents to coordinate attacks, swarm on targets, and adapt rapidly to changes in their enemy's tactics, all at minimal cost and risk... this evolutionary leap in the methods of warfare makes it possible for extremely small nonstate groups to fight states and possibly win on a regular basis."
So far at least, no state has been beaten by ISIS. They've moved into situations where there was already a civil war. Nor have they been able to put together a state. And the terror they've produced is so tiny that the media describes each of the victims. This is not war, it's not even a small riot. It's just a media circus.
For example, ISIS appears to have adapted to the air campaign. They've melted into the local population and they don't mass to form large targets.
This strategy is possible for terrorists but it doesn't work for a state. To survive, a state has to protect its civilians. So ISIS melts into the local population? When the US and Britain firebombed Germany they weren't worrying about the Nazis melting into the local population. During war you kill them all and let God sort them out. ISIS can't protect their civilians therefore they cannot fight a war. War is mass murder. ISIS's civilians aren't being targeted because there is no real war. It's a media circus, a propaganda war.
In Saudi Arabia and Jordan I think they'll avoid major confrontations and instead try to start a civil war against "corrupt" monarchies. Believing that Saudi Arabia will survive intact is taking a bet that the House of Saud, a rich corrupt family of aristocrats will buy there way out of trouble or sacrifice their own people in an all out total war to save their skins. I don't know if I would put a lot of money on "monarchs" surviving in the 21st century, much less a corrupt authoritarian absolute monarchy.
I agree, Saudi Arabia and Jordan could fall at any time and without much warning. They could fall without ISIS being involved. And the worst case, as far as ISIS being a threat goes, would be ISIS taking them over. Could that happen? Maybe, but the public relations department at ISIS is the worst I've seen since the Mexican drug cartels who advertise by decapitation. What ISIS propaganda is doing is making enemies not taking territory.
But suppose that ISIS does pick up Jordan and Saudi Arabia. These are inherently weak countries and cannot support any real war. Neither of them has any significant war industry (nor is there in the rest of ISIS territory). Jordan imports 87% of its food and Saudi Arabia 70%. A few months after the start of a real war the few units they have left will be out of ammunition. Their civilians will be eating zoo animals and pets (followed by much worse) and morale will collapse. The problem ISIS has is that they cannot protect their civilians. Nor can any of the Arab states. The way the media paints it, it is the modern industrial democracies that cannot protect their citizens from ISIS but in truth it is the reverse. And the vast majority of civilian casualties are being taken in ISIS territory not France or Britain.
That said, I'm not making any bets that ISIS will win, just yet. The bet would be like buying some long dated OTM crude, /CL, calls. But, I think you have to consider the possibility and perhaps take a small long-term /CL trade if you sense that ISIS is getting any traction in "The Kingdom."
I don't think it's a bad bet, but you should have plenty of warning so you shouldn't have to burn a lot of time premium. And I would take profits before war actually begins.
A Saudi collapse would make the 1970s oil squeeze look very mild. And I think it would be the beginning of a real war. If the US government has any sense, the first thing they'll do is rationing and price controls. But the full territory that ISIS is claiming (i.e. Morocco east to Iran or India, I forget) is so militarily weak that I can't imagine a war lasting more than a few years.
We're in peace right now (thank God) and it's easy to forget what war is like. The first thing that collapses is international trade and the oil trade above all else. Military might determines where oil goes in wartime and that's a matter of "blue-water" navies. Same happens with food, minerals, etc. China would be in deep trouble, along with all the little unaligned countries that don't produce their own oil. In fact, people think of China as preparing for war but if they are, they're doing a rather mediocre job of it. They're becoming incredibly dependent on trade that they cannot possibly protect.
