So what's so different about that and the US officials who plotted to assassinate the Iranian General Soleimani?
If the US can do it, why not India?
US does it in broad daylight with full ownership. When Canada alleged involvement of Indian Govt. in killing of their citizen, they were caught off guard and became very aggressive in their denials. Why didn't they accept it?
Pick apart everything that's wrong with the analogy you just made, and you might have your answer.
