@ Mujib was not a agent of India. Yes, it was true that he used to take help from him earlier before mid 1970. But once Republican govt came to power in USA the whole equation changed in Indian Subcontinent. Actually, Mujib was a creation of CIA and RAW once India and USA were a good friend. Both they wanted to halt the Pakistan tilting towards China. So, to have balance Sk Mujib was picked up. Mujib's role after general election of 1970 and once he became a PM and President of Bangladesh proves such idea.
@ He tilted towards Russia and Socialism just to come out from the clutches of RAW and finally from mighty India.
@ CIA killed him as because he was not keeping the interest of USA in South East Asia. USA badly need a logistical base in and around Bangladesh just to continue the Vietnam War. Instead of helping USA he was moving towards USSR.
