Gosh, how many kinds are there? Shaped charge?
Anyway, just sticking my nose in where it doesn't belong. Nothing personal. I't's too serious for me....this discussion. I'm not imaginative enough to foresee the situation in 2007. If other nations lose respect for the US, then I would say something like being nuked is a distinct possibility. If that happens, nothing we could do could stop it if we didn't react quickly and with equal retaliation. This was understood by the Soviets and China. Why do you think the Soviets backed down during the Cuban Crisis. China doesn't even need nukes if we were in a war with them. They could beat us with sticks.
Terrorist countries should learn from them, at least as far as watching out for their own population when it comes to using nukes. Let's hope and pray Mid East countries are smarter than to do that.
