New Treaty Banning Cluster Bombs?

Hopeful news from a conference in Norway regarding the issue of cluster bombs. According to the BBC:

Forty-six nations, including the UK, have pledged to work towards a new treaty banning cluster bombs.

At the end of a two-day conference in the Norwegian capital, Oslo, the countries signed a declaration committing themselves to a ban.

As always, there is a dissenting voice:

The US has rejected any ban, saying the weapons have a place in its arsenal.

But the US aren't alone. Japan, Russia and China also refused to play any part in the efforts to ban their use. It is about time that these indescriminate weapons were banned. One only has to look at the situation in Lebanon to see the effects on the civilian population. They have no place in anyone's arsenal and there is no justification for their continued use.
