you literally wrote
"There is no possibility of a second strike once Pakistan launches a nuclear missile against India." in response to a comment by me about Second strike, so don't gaslight. lol
You don't know what you are talking about. lol
Believe what you want to believe.
No first use doesn't means they refuse to use Nuclear weapons, but that they won't use it first, this isn't really anything new, its common among states that have an advantage in conventional means. A state which doesn't have a conventional advantage is one that explicitly lays out that it will use nuclear weapons first, and it defines red lines and thresholds for its use, and typically concentrated on building tactical battlefield nuclear weapons deployment. Its thresholds for use in its doctrine are far smaller than a state with a no first use policy. For example the Russian doctrine compared to the US.
