In my opinion the Government has to do just two thing: give security to people (police force) and an adequate legal system. All the other things can be done by the private sector and even the two things mentioned before can be done by private companies. I am not Keynesian. I don't believe in the government intervention. I believe that politicians have their own agenda and it is not helping people but to be elected.

Tools of foreign policy would include sending in diplomats to try to negotiate peaceful terms.
