Also, it's just a (prestigious) prize. Keep doing science, don't think about it. And for god's sake, don't come up with science policies that 'will make our country win more Nobel prizes'.

'More Nobel prizes to our country' is therefore hard to accomplish by politicians (and sounds populistic). Instead of using the Nobel prize as a rhetorical tool, politicians would probably do better to foster good science in general. Keep universities healthy, leave the policy making to scientists instead of pointing out areas that are going to get increased funding. Make sure scientists can investigate whatever they find interesting based on scientific quality of a proposal/track record. Maybe do keep a check on scientific nepotism et al.
Both being a scientist and defining a proper science policy are hard though.
