One thing that the US does pretty well is opening up data and code after a gov project is finished.
Not true at all. For one, the Constitution and various Federal and State laws allow elected persons to take an affirmation instead of an oath, and Article Six of the Constitution specifically prohibits a religious test on any public office.
Second, you may find http://www.americanhumanist.org/HNN/details/2009-12-can-an-a... to be an interesting read on the topic.
Third, just because atheists are not elected doesn't mean that they aren't allowed to be elected—just that most people in the US want a religious leader (or that not many atheists choose to run for office, or that religious politicians have more popular plans, etc.)
Anyway would anybody clame that the US is the show of stat for seperation from churge and state?
So most of these stupid rules flow into other nations too. To other western government I would say stop listen and looking to amerika. If you want to look somewhere look at the countries that work well.
For Drugs look to Portugal, For democracy look to Switzerland, For Prisons look to Norway, ..., and trie to improve upon it. There is almost nothing I would copy from amerika if I would "create" a new country.
