Is It Possible to Assassinate an Indian Prime Minister?

It is a little far fetched to believe that the. americans, who were already engaged in this massive cold war with the soviet union,. would have been able to assassinate an indian prime minister on russian or on usar. So i would say that it's not entirely impossible. Especially in the case of homi baba. It is very suspicious the way the plane crash happened, in the way he died, and and there was no investigation conducted either from india or from err from france or switzerland, or from any other country. There are lots of unanswered questions. Are there? Questions that have still not been answered?
