Just a quick addition to the landmine discussion -- although the U.S. is portrayed as the big bad guy for not wanting to sign, other states -- notably Finland -- have signed the export ban and are considering caving on the production ban because they have enough land mines already.
Land mines are a part of a defense plan. If you have one static border to defend, you can mine it, forget it, and sign any treaty you want. If, like the U.S., you sometimes want to deploy your army to places you haven't been before, you have to be able to put new land mines in. So in fact, a ban on land mine production is really (like the ICC) another European attempt to prevent American "military adventurism."
