You are worried about nothing. Some of the most talented people on the planet who work in International politics for dangerous war zones end up living in the Hague (one of the prettiest places in Europe, in the Netherlands, a perfectly lovely country), London, Hong Kong or Singapore, etc.
This is what you are devastated about? Good grief. Do some research. If she’s planning on becoming a foot soldier for a UN Peacekeeping force (a job for which you do not need a college degree) then your fears are founded. If she’s interested in policy, negotiation, strategy, and the like (i.e. the careers for which you need a college education) she will likely end up living somewhere lovely and safe at least most of the time.
And you do realize that the likelihood that she’ll change her mind and end up at the World Bank or Unicef doing development economics is extremely high?
