China, India and Pakistan's nuclear triangle grows more complex after new defense pact

Pakistan, Turkey and Saudi Arabia signed a mutual-defense pact in Mecca last week, agreeing that an armed attack on any one signatory would be treated as an attack on all three. The three governments described the agreement as defensive in nature and said it was not directed at any particular state.

The pact lands against the backdrop of the decades-old and often tense nuclear dynamic between China, India and Pakistan. Analysts said that relationship has long carried inherent risks, and the new three-way alliance introduces an additional variable into an already complex regional balance, even as its precise military implications remain untested.

For India, analysts said the pact's significance lies less in whether it would ever be formally invoked than in how it could shape longer-term regional security calculations and alliance-building among neighboring powers. New Delhi has not issued a detailed public response to the agreement, and officials in the region are expected to watch how the pact's terms are interpreted in practice.
