Himalayas, no more the defence barrier

[sjalal19]

correction... khyber pass is not in himalayas its between Greater Hindukush and Spin Ghar(koh e safed) ranges.

Correct you are. I meant the mountainous range of greater Himalayas ranges extending southeastward across northern Pakistan, northern India, and Nepal before trending eastward across Sikkim and Bhutan and finally turning northeastward across northern Arunachal Pradesh throughout nearly all of its length it adjoins to the north the southern Tibet Region of China. Theoretically you are correct and I stand corrected.
