If you are that paranoid about chinas evil intention on CPEC for pakistan and that the project will destroy pakistan, then by all the means ask your gov to stop it. Currently, pakistans constitution doesnt allow foreign troops to station in pakistan or make pakistani soil a foreign military base, you are talking nonsense. You are more talking like a hindutva looking from india and US interests. Chinas survival doesnt depend on gwader supply line in the future, period, but has something to do with the secure russian supply lines, but not entirely. China can find its means for survival such as mutual assured destruction of US in times of war, dont belittle chinas capability.
