I don't have any confidence that we would know all the details of what's being monitored by intelligence services, but my sense is that we should not be confident that we can block them through banking sanctions, for example. They have been able to rob banks, literally, and they've been able to collect sufficient funding in very small ways through coercion and intimidation.
Some people have interpreted their demand for $200 million for the Japanese hostages as a sign that they had at least temporarily run out of money. They have big swings in whether they're feeling financially secure or not. But I think they're operating in an environment in which they are more mobile than we can stop them from accessing whatever resources are available locally. Unlike Iranian sanctions or Russian sanctions, our capacity to intervene from afar and stop the flow of finances is not likely to be completely successful.
