Arent cluster bombs banned after the bombarding of serbia in the '99 ?
There is a convention on cluster munitions but...
only the countries in blue and purple have aggreed. As you can see, the countries with the largest militaries have not.
Also, there was a controversy in Canada a couple of months ago because our government uses a loophole in the convention that allows us to operate alongside allies (such as the USA) which continue to use cluster munitions. This isn't something I have followed too closely - I think it's moot. ie Let's keep on killing each other but make it easier to clean up afterwards. Ditto with landmines.
