Nasr argues against the concerns expressed by others (see this and this) that the recently ceasefire agreement concluded by Russia and the US was a mistake, that Turkey, Saudi Arabia, and their sponsored terrorist armies would simply take advantage of it. It appears that "Plan B" is the outcome most preferred by the US, and Nasr reminds us that this plan represents a strategy that has also been favored by the Empire throughout recent decades:
It should be noted that partition is, and has been for a while now, a central part of U.S. foreign policy strategy for dealing with the recalcitrant “regimes” and inconvenient population groups.
Whether it is Sudan, Yugoslavia, Serbia itself, Macedonia, Ukraine, Russia, China, Libya, Syria, Iraq, Yemen or Iran, the methods, and the eventual (or hoped for) outcome of partition vary only slightly. In some cases direct military intervention is required, but in most cases local proxies will do nicely, whether armed militias or "civil society" types.
