These are the same bunch of people, who were also there when Modi came last time around. Clearly looks like a paid job. We are talking about the greatest showman India has ever produced. Anything is possible.
The event was organized by a Texas Oil Lobbyist. So, you can understand how much is at stake in this event. Modi declared that they will dump Iran and buy oil from Texas, USA refinaries in the future. Also, Modi endorsed Trump on behalf of NRIs during the event by proclaiming Abki Baar Phir Trump Sarkaar! So the event was a win win situation both of the leaders.
