> Because the US is a sovereign state, which means they have jurisdiction over whatever they choose to have jurisdiction over, subject to constraints forcibly imposed by outside parties.

I am afraid this is not correct. A sovereign state has jurisdiction over physically defined borders ( boundaries) of the state. Thus, US can not claim its jurisdiction over India because US is sovereign state. In case o Credit Suisse , since they are doing business in US , US does have jurisdiction on CS US entity. I believe though, US has no jurisdiction of other parts of CS that don't exist in US.
