I have been getting some interesting emails from a group called Survivor Corps. They are working to ban cluster munitions. I don't think they will be successful as cluster weapons are designed to kill over large areas and they are very, very good at that. They are also very good at taking out armor, aircraft on the ground and hard points. This is a lot like the land mine debate. The weapons are terrifying and for good reason. That is part of why they are effective.
The problem with both weapons systems is that they don't POP 100% of the time and can lay inert for years until some unfortunate soul who had nada to do with the prior conflict is killed or maimed by one. There are areas of the world where they litter the countryside like poppies. Afghanistan, Bosnia, Lebanon, and Myanmar are a few of them.
Even rifle rounds are not 100%. That is why any good soldier will clean and inspect every round he has in his ruck before he goes into the field. If it looks the least bit dodgy you toss it. Pilots and artillery men are usually the folks operating the delivery systems for cluster munitions and they can't inspect every bomblet as they are sealed in a canister.
Look at their site
and make up your own mind. When you are up against bad guys and an A-10 Warthog comes in and drops a few hundred of these on them you love these things. It's when you have to MCAP the place later that you hate them.
