WI the Swiss never federate in the 19th century and remain a loose confederation?
Sure, its Switzerland, post renaissance they've never exactly rocked the boat so the impact won't be on a par with other nations not unifying. But still. The effect of having a bunch of small, semi-united statelets filling in the area rather than a strong neutral capable of putting up a fully unified defence, could have a bit of an impact whenever any of Switzerland's neighbours feels a bit ethnic nationalist.
