> then the logical solution is to make sure they get that $100M immediately.
What? No, that's not the logical solution. Have you considered the consequences of paying that money beyond the immediate deaths? You've suddenly put a real price on terrorist attacks - as in, if I decide to go through with a terrorist attack after 9/11, I know that I can extort the country for anywhere up to $100m. Hell, everybody with a grudge against the US suddenly has massive financial incentive to carry out attacks against the US. How many more people will die because you've decided that it's okay to pay terrorists?
They don't just disappear- the money is probably going to be marked, the people will be eventually traced and dealt with. Money is very traceable.
There are plenty of people with a grudge against the US, some of them quite rich. US foreign policy made sure of that. Extra 100 million would make no real difference. The thing stopping them is distance to US and threat of deadly force.
