They are supporting Pakistan in all issues against India placing military assets against in Pakistan . Giving nuclear weapons to Pakistan while they steal territory in the East. They may not battle India directly but they are making a great effort to make sure Pakistan is completely able to destroy india
World is getting over with nuclear hangover/ deterrence. Thinking about two nuclear country attacking and mass mobilizing in 90s would have been seen as a global crisis but today world is becoming different. Russians engaging against American interest in middle east. Chinese directly supporting NK and Pakistan with nuclear equipments and going into bloody conflict with india.
Recent dreams to dominate south China sea with American and Chinese naval forces eye to eye against each other.
The level of deterrence in few decades will be established again with hypersonic Nuclear weapons with much more advanced war heads.
Pakistan in past got access to nukes because of American dependence on Pakistan and Chinese TOT.
India today must openly make efforts to stop Pakistani advancements in development of these systems even if requires pro active steps like what Isreal is doing against iran. Clear and simple message to Chinese should be given if provide TOT to Pakistan then we will field more and more number of missiles towards you ultimately undermining your security.
World would definitely not want india to develop these capabilities but we must be among top 3 to develop these system.
Even USA would not like india to develop these system.
But Americans leaving Nuclear treaty shows how thing's are changing with Russians and Chinese doing new testing and developments. Americans also want to do catch up.
