i do think india pakistan bangladesh and srilanka are countries with the least jewish influence ,but there were many jews ealier in india but i am not sure about it in the present scenario.
At the time of independence there were around 40,000 Jews in India, and most of them were concentrated in Bombay and Cochin. But after Israel was established, many of them immigrated to that country. Right now only around 4,000 Jews are left in India. But one interesting story is that of some 3,000 Bnei Menashe Jews, from north-east India. These are mostly Kuki-Chin people who recently converted to Judaism.
