No doubt some countries are acting swiftly, while others are letting the terrorists draw out their money before they "block" them. With Switzerland, it could have gone either way, because I'm sure they are with us on the terrorism issue, but they also rely on banking privacy for their economic lifeblood.
There was an article I saw yesterday, but did not post, about Italy approving legislation to begin seizing accounts.
These things take time, unfortunately, but we are slowly squeezing off the financial lifeblood of the terrorists.
Eventually, all the banks will comply because we will cut them off from the US banking system if they don't. None can survive that for an extended period.
