Whilst I agree that the European ATP has a claim to an equivalency with some degree levels the US ATP most definitely does not. When converting to an FAA ATP back in 1999 I completed my ground exams in one sitting on a computer in 40 min and achieved 87%. Little more than doing a PPL in Europe and a world away from my UK ATP sat in the 80s.
I wouldn't want to get into a pointless discussion over which system is better but responding to the original question posed I would say.. European License; Yes. FAA; No
