Meanwhile, supported by aid from China and the Soviet Union, North Vietnam strengthened its air defenses. By November 1967, the number of American troops in Vietnam was approaching 500,000, and U.S. casualties had reached 15,058 killed and 109,527 wounded.
India is one example of a subcontinent because it is a part of the Asian continent. Its landmass is not connected to the Asian continent plate, thus not part of it. India is regarded as the largest nation in South Asia and also known as the South Asian subcontinent. The term is used culturally and politically.
Geographically, it is the peninsular region in south-central Asia delineated by the Himalayas in the north, the Hindu Kush in the west, and the Arakanese in the east. Politically, the Indian subcontinent usually includes Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. Sometimes, the term South Asia is used interchangeably with Indian subcontinent. There is no consensus about which countries should be included in each.
