Yes, yes, I know, if you buy a ticket from a DB reseller in the US, and get hit by a train on a platform outside Heidelberg, locus of the action is entirely Germany and first venue, if not all venue, should be Germany ...
I am not a lawyer, but if you flew CDG-MEX and want a US court to enforce a luggage issue on the basis that you bought the ticket in the US I think you'll have quite the uphill journey, with outlays exceeding what you can possibly hope to recover. But that is just my opinion.
