Oh, wait a moment, may be the Swiss people have problems with identities. Switzerland itself doesn't have enemies nor allies, it's just neutral. Switzerland doesn't even has its own language, people there speak three or four different languages. Yet, the people there are not French, German, Italian, Romanian, nor Swiss. In fact, this diversity makes the question of a national culture a recurring issue. It's just like water, colorless, odorless, and tasteless.
So, may be that's why they want everything to be just neutral and with no identity. Everything including the buildings there.
