I just looked, US News ranked ETH Zurich as #29 globally, but Univ. of Amsterdam is #39, Univ. of Copenhagen is #42, and then ten more European[0] universities before getting to the Univ. of Zurich at #67 overall. I scrolled down a ways further but didn't see any more Swiss universities listed. [0] I excluded the UK but I'm not going to check which Nordic countries are EU members. It's well-known that the US News rankings have their problems, but it seems like they'd have to be really out of the ordinary in order to support your claims.
