Which move by India is the greatest shock to Pakistan?

One of the greatest shocks India has given to Pakistan is the revocation of Article 370 in August 2019, which removed the special status of Jammu and Kashmir. This move was unexpected and significantly altered the geopolitical situation in the region. It weakened Pakistan’s long-held stance on Kashmir and reduced its influence internationally. Additionally, India’s rapid economic growth, military modernization, and strong global partnerships have further shocked Pakistan by widening the gap between the two countries in terms of global standing and influence.
