It helps to be familiar with realism in international relations theory starting with Machiavelli and Hobbes, and postwar realism which developed over the Cold War. The ethics have been debated for centuries and the mainstream interpretation is that leaders have a fiduciary obligation to the population they are responsible for, which fundamentally changes ethical considerations.

It’s a completely different moral question when you’re responsible for a billion people, many of whom may suffer or die due to the cost of fuel. It is in principle a violation against their own people for Indian leaders to prioritize Ukraine’s people over their own.
