Comedy, the UN is undermined by no action on Syria... The UN is undermined by the fact that it relies upon the whims of those who pay the bills and provide the troops, the lack of consistency in effecting humanitarian interventions i.e. ignoring massive death totals as long as they aren't in strategically important places (see former point), and in fact, a piss-poor human rights record full-stop. UN sanctions on Iraq led to 500,000 deaths in Iraq and which prompted Halliday to resign saying "I don't want to administer a programme that satisfies the definition of genocide". The UN is and always has been a farce. In theory, it's a good idea. In practice it has caused at least as much misery as it has prevented, probably more. Even so, Ban Ki-moon is against military intervention so I don't know how it can be claimed that it's undermining the UN to be against military action.
