When does a government have the right to interfere in the actions of another government, in order to provide relief for natural ( and other ) disasters, and to preserve human life and liberty? (BB)

The official (UN) response to that question is (I think) "never". My personal response is "extremelyy rarely" and even then I'd much prefer a UN vote (scrap the vetoes in favour of a say 3/4 majority vote) and an international action instead of the action of a single government.

In Turkey, wearing a headscarf in government buildings is (now again) forbidden. Would that give say Iraq the right to interfere on the side of religious liberty. Would Germany have the right to attack say Saudi Arabia when a public stoning is scheduled?

Such a world would be a dangerous world. I prefer the present one with all its problems, not the least among them standing by in inaction seeing people dying that a better government could have saved.
