Good speech by David Cameron to the UN:

In his first speech to the United Nations General Assembly, the UK PM urged the UN to be "united in action".
"To fail to act is to fail those who need our help," he told the Assembly in New York, saying the UN needed a "new way of working".
In his address, the prime minister said nations must be prepared to act and not just sign resolutions. He said the UN had played a vital role in Libya but it was only effective when nation states were prepared to enforce its wishes.
Mr Cameron said: "My argument today is that Libya and the Arab Spring shows the UN needs a new way of working.
"Because the Arab Spring is a massive opportunity to spread peace, prosperity, democracy and vitally security, but only if we really seize it."
He went on: "The UN has to show that we can be not just united in condemnation, but united in action, acting in a way that lives up to the UN's founding principles and meets the needs of the people.
"You can sign every human rights declaration in the world, but if you stand by and watch people being slaughtered in their own country, when you could act, then what are those signatures really worth."
