Yeah, you have to handle the hand you're dealt, but that doesn't mean you can't change the hand, given time. Most countries has managed at least one peaceful re-organisation of the country by now (the US has had several - the north and frontier switched from slave states to free states, the Human Rights movement, arguably the current neoconservative surge et c), and countries change their culture all the time, constantly.

Heck, the entire point of democracy is that you are supposed to be able to do peaceful re-organisations of the country.
