China says will not support sanctions on Iran at this time - fuel swap best option they say as do many 'key' players at UN- but this option to me clearly a fall back position for Iran ie if sanctions leveled then they will agree to fuel swap, which of course will be a diversion from real intentions - this seems obvious - China will not get in way of Iranian nuke ambitions - Iran is gaming the 'system', as are all parties in opposing prompt action re sanctions.
But what can be the logic for a delay on imposing sanctions when, viewed objectively, the need for such should be obvious? Only that there is a related issue which the reluctant countries care about more - America - and that says to me you can forget about any degree of diplomacy solving this problem because how else other than by a complete surrender by the US [and consequently Israel] which ends with Iran getting the bomb can these anti-American desires be satisfied?
