I live in Finland and there is an emerging start-up scene here already. Also there are plenty of older, steady-going companies, that have proven business models, who have start-up mindsets towards new things.
If your plan is to create a thriving project that aims to address a specific business problem, you are going to need a group (even small) of likely minded people. There should not be any "work for food"-ethics attached. No body will work for you for food, but many people are willing to work to create something they believe in.
Why exactly do you want to be in the US? I've lived in Moscow and St. Petersburg for quite some time. It is hard to imagine, that you won't find anyone in those cities with summed population of almost 20 million, who is willing to work with you on your or their ideas.
