This is not the first time they shed a bit of light on this... My take on it is that certain tendencies within the US capitalist class and their political lackeys may want to put an end to this conflict. The factors at play here imho are, in no particular order: 1) internal economic contradictions 2) a possible conflict with Iran right around the corner (hence - their Zionazi outpost would demand more weapons if not direct US involvement); 3) a need to have some weapons stockpiled for aggression toward China and 4) (plausibly) political - presidential elections
