Picture this: you're at a big family gathering, and your cousin is being bullied by a group of rowdy relatives. That's kind of what was happening in East Pakistan (now Bangladesh), where the local population was being oppressed by the Pakistani government. The Awami League, led by Sheikh Mujibur Rahman, was fighting for independence, and India decided to lend a helping hand.
It's like when you're playing a game of chess, and you need to make a strategic move to outmaneuver your opponent. That's exactly what the Indian government did, by providing military support to the Mukti Bahini, the Bangladeshi freedom fighters. This move put pressure on the Pakistani Army, which was already struggling to maintain control.
