I&#x27;d shorten the list to one significant difference that&#x27;s somehow avoided - Europe consists of different countries, with different cultures, interests and languages. That&#x27;s one of the beautiful things in Europe, but let&#x27;s not pretend it doesn&#x27;t exist. Forget laws, they can be written, changing culture, interests and financial situations is huge. There is no country called &quot;Europe&quot;.<p>But to do business through all European union, there&#x27;s way more added issues at the beginning then compared to Silicon Valley vs. US (similar culture, values, interests, language) or eastern countries (China, Korea, Russia and their markets).
