I think the question is referencing the media’s coverage of how India has been applauded for going nuclear, but when their neighbor, Pakistan similarly did it, western countries expressed concern about their (Pakistan’s) technology getting into the hands of terrorists, since Afghanistan borders Pakistan.
The United States has shown preferential treatment to India in it’s nuclear achievements, and contrastedly, expressed concerns about India’s rival, Pakistan, reaching the same milestone for its country at the same time.
