Imagine you are the most powerful person in the world. You can sanction countries, move armies, and shake stock markets with a single tweet.

The United States Supreme Court, in a historic 6–3 ruling, told the most powerful president on earth that his tariffs were illegal. And the world, including India, is still calculating what this really means.
