But, Indira Gandhi missed a nice chance to get back Kashmir during 1971 war for getting Independence for Bangladesh.
The army of Pakistan were literally curshed by Indian army from all the sides - air force, military, naval force...Pakistan was literally pleading to stop attack. Indira Gandhi should have made use of this situation to end the Kashmir issue...She just stopped after getting independence to Bangladesh (East Pakistan)..
Another mistake which Indira made was allowing Bangladeshi refugees inside India. Also, she didnt ask them to return back to Bangladesh after getting independence.
Now, bangladeshis are joining hands with Pakistan & Kashmiri militants and bombing India (which got them independence)
