An ethical foreign policy?

How to become the pariahs of the modern world. The Guardian reports:

'Britain has joined the US, China and Russia to block a proposed ban on cluster bombs in the wake of extensive use of the weapons during the war in Lebanon.
A group of countries, led by Sweden, is urging a worldwide ban on cluster bombs at arms talks in Geneva. Each bomb contains hundreds of small "bomblets", many of which fail to explode until picked up by inquisitive children or stepped on by civilians...
The Foreign Office confirmed that the UK is opposing the diplomatic push led by Sweden in Geneva to change the ... conventional weapons treaty.
It said: "The UK believes existing humanitarian law is sufficient for the conduct of military operations, including the use of cluster munitions, and no treaty is required. The UK remains committed to improving the reliability of all munitions with the aim of achieving lower failure rates and leaving few unexploded ordnance in order to minimise the humanitarian risk." It said this had been longstanding British policy.'

Have they no shame?
