Considering the number of downvotes, i guess at least 3 americans got hurted by my comment. Sorry for this. All i know is that if a business is based in germany accountancy is a lot easier and i might be able to recover VAT and other stuff. US weird invoices cause problems on this side.

That said, if i get (as an example) a search warrant from a US court and i'm based in EU, i will simply ignore it. This is quite enough.
