Whakaotihia te rerenga e whai ake nei: Mai i te Independence India i whai i te kaha karihi. I whakaaro a Nehru ka taea e te kaha karihi te kawe i te whenua ki mua me te awhina ki te whakatutuki i ona whaainga whanaketanga. No reira, ka tiimata a Nehru ki te rapu awhina mai i te United Kingdom, Canada me te USA. I te tau 1958 i whakaaetia e te kawanatanga o Inia me te awhina a Homi J. Bhabha te mahere whakaputa hiko e toru-waahanga ana ka whakatuhia te Whare Rangahau Nuclear i te 1954. I kite a Indira Gandhi i te whakamātautau karihi tonu a Haina mai i te 1964 ki muri, no reira ko te riri ki te India. Ko te hua, i whakahaerehia e Inia he whakamātautau karihi i te koraha Pokhran i Rajasthan i te Mei 18, 1974 ka tapaina ko Operation Smiling Buddha. I kī a Inia ko te whakamātautau mo nga "whakaaro rangimarie". Heoi, i aro atu te whenua ki te whakahe, a, i whakamutua e te United States me Canada nga tautoko katoa ki Inia. Ahakoa te kaha o te whakahe o te ao, he rongonui te whakamātautau karihi i te kainga, i puta ai he whakaoranga wawe o te rongonui o Indira Gandhi, i tino whakahekehia mai i ona taumata i muri i te
Te pakanga o te tau 1971. I muri mai, ko te whakawhitinga ki te kawanatanga mo te Tai Tokerau o Inia i whakahaerehia e tana tari. I te tau 1972, i whakawhiwhia e Indira Gandhi te mana ki a Meghalaya, Manipur me Tripura, i te wa i kiia ai te North-East Frontier Agency he rohe uniana ka tapaina ko Arunachal Pradesh. I whai ake tenei i te whakaurunga o Sikkim i te 1975.
