It's not just Delaware. There are a bunch of other states, e.g. Wyoming, Nevada, Florida, etc. Having said that, it's not a tax haven if you're a US resident for tax purposes (then you're completely screwed). If you're a European with no ties to the US however (no residency, work visas, or US parents that can tie you to nationality by inheritance), then you can incorporate or stash money in the US in complete anonymity. The US won't easily (at least not on a fishing expedition) give out your information to your government. (And I'm guessing your concern would be hiding money and information from your own government rather than the NSA).
