What is the name of the country that conducted its Nuclear Test and became a nuclear power state soon after India conducted its second Nuclear Test?

Pakistan

In May 1998, India conducted a series of nuclear tests, showcasing its ability to harness nuclear energy for military purposes. This move was mirrored by Pakistan shortly thereafter, escalating the potential risk of a nuclear conflict in the region. The global community strongly criticized these nuclear tests in South Asia, leading to sanctions imposed on both India and Pakistan. However, these sanctions were later lifted.
