> Why is it that more developed nations have to find solutions for failed states by re-homing the population which voted for those same policies instead of leaving them to fight and improve the conditions in their own countries.

Because developed nations have a vested interest in keeping international peace where possible as it is good for trade and national security.

You’re also assuming every country is a fair democracy, and that they can resolve issues without international support.

Remember that every developed country (including your own) has only been able to develop by leveraging cheaper labour and goods from 3rd world countries over the past 300 years, we are all very closely linked, whether you like it or not.
