Also assume that Russia times the Arctic based attack to coincide with multiple mass explosions in USA cities organized by the Islamic State, using their cells who are already here. A scary scenario. But I’m sure the Bamster has a handle on it. Anybody want a free Obama-phone? How about another EBT card?
Actually, that is my view. If a major power such as Russia or China were going to take us down, I have no doubt they would do exactly as you say, use arab proxies who would gladly martyr themselves in the process and gladly take the blame.
A nuke in half a dozen port cities simultaneously would take us off the world stage for a decade or two. We'd take our revenge against the obvious perps while the actual perps offered help and sympathy. Then we would withdraw our forces from abroad while our economy recovered over the next 25 years leaving the rest of the world to sort itself out without us.
The economic collapse here would be the perfect stage for radical parties, some of which would be directed from abroad. We would either see the rise of a good autocrat or a very bad one.
