US is worried about the rise of China.It wants India in NATO so it can surround China like it has encircled Russia.However Indians are very shrewd.They will not join any camp not yet.In future if they get scared then they may join NATO.No one invites Pakistan to join any bloc.The Pakistani generals and political mafias destroyed Pakistan.The generals and political mafias were in power for equal number of years approx 30 years each and made it a beggar.
Nations that are independent and self-respecting, put efforts into improving their country's image and citizens' welfare without any external pressure.
As opposed to Pakistan, where our corrupt prime minister claims that "beggars can't be choosers."
