In the real world I am no isolationist, there is international law that regulates when the sovereignty of a nation can be violated. Withholding medical assets is not a trigger, otherwise you could invade any country that has pharmaceutical companies.
Trek is what you call isolationist, the Federation has no right to mess with other cultures in any case. Not when there is are devastating wars and certainly not because they withhold a medical asset.
So your position is violating law in the Trekverse as well as in the real world. To pretend that you are actually doing something ethical while ravaging and raping people is a bad joke at best.
