@cicerone imposter,
It seems to me, from what I've read in news reports, that the UN is doing all it can in the circumstances.
Definitely not as much as it
could, if its hands were not tied by Russia & China's veto powers on the Security Council, that's obvious ...
It has installed UN observers in Syria (some of whom were recently shot), to monitor developments "on the ground".
It has been using its influence to rally support for sanctions against Assad's government.
It is attempting to involve Iran in negotiations in an effort to avert a civil war in Syria, given that Iran has been actively supporting Assad's regime. However the US (Hilary Clinton) appears to have objected to Iran's inclusion in any such talks, so that may not be possible if US uses its veto power on the Security Council.
It is applying pressure on Syria's ally, Russia, in an attempt gain support for action against Syria in the Security Council.
And (very important I think) it has recently negotiated with Assad to allow emergency aid workers to work within Syria "without hindrance" ... so that the civilians affected by the recent attacks may receive urgently needed humanitarian assistance. (let's hope that Assad doesn't renege on
this agreement, too!)
Given that the Syrian government has reneged on it's ceasefire agreement (UN 6 point peace plan) & is continuing to massacre civilians following Houla, what else do you suggest the UN could be doing right now? That is actually doable within its current charter?
I'd be interested in your thoughts.
