Be careful of the Hitler quote - it is bogus.
Also, be careful of the Switzerland usage as the reason Hitler didn't invade. He didn't have to as the Swiss collaborated to a very large extent. Hitler also said that when he was done with Russia and the UK, he was going to clean the Jews out of Switzerland and didn't see one bit of problem in taking the country.
That's why go with legit scholarly sources and be careful with Internet ramblings without being really well sourced.
