What if Pakistan and China declare war against India today?

CHAIN REACTION

The Indian military will go on full alert and will deploy troops, tanks and missiles closer to the Chinese border in Arunachal Pradesh, Aksai Chin and Ladakh region. The vast flat valleys along the mountain ranges in the Ladakh area will allow for armored movement by both sides across the border.

The Chinese Air force in the Tibet region will launch airstrikes against Indian troops along the McMahon line- Arunachal Pradesh/ Zangnan- Aksai Chin area. Also, a contingent of Chinese fleets would deploy to the Greater Indian Ocean to confront the Indian Navy which may attempt to block Chinese oil supplies from entering the Strait of Malacca. China would utilize a large fleet of frigates, destroyers, and submarines due to the vast Indian Ocean.

The Militaries of U.S., Japan, Taiwan, Vietnam and South Korea will go on high alert, to match the posture of the Chinese armies. If Chinese missiles hit Japan or South Korea, expect both countries and the United States to retaliate in kind.
