In EU law all payments get pretty much the same protections as USA credit card payments, even for debit cards the customer is legally out at most 50 EUR, so there is no advantage in it being a credit card.
The motivation of Chip&PIN in EU is driven by the fact that banks are forced to cover most of the fraud costs (as opposed to USA, where much of stolen card fraud is forced upon merchants), so they have a motivation to actually prevent it; and the inconvenience of PIN is mitigated by highly prevalent contactless (and PIN-less) chip payments for small transactions.
