What are you talking man ? I am quoting scenarios when that influence was used. List the top 10.
1. India supported Vietnam's independence from
France, opposed American involvement in the
Vietnam War, and supported unification of Vietnam. During the Vietnam War, India supported the North, albeit not by conducting military hostilities against the South. This can be contrasted with the policies of the US, who strongly supported the South and engaged in military conflict with the North, albeit without issuing an official declaration of war.
2.1971 war Liberation of Bangladesh
3. LTTE, Not the best example, but there you go... and it happened. LTTE was also destroyed using help from India
4. India's economic presence and goodwill in Afghanistan has grown considerably ever since 9/11
5. Farkhor Air force base along with Ayni Air force base in Tajakistan is operated by IAF along with Tajakistan Air force
6. Sri Lanka freeing considerable amount of Indian fisherman after speaking with the PM directly, it has happened more than once already. Also conspiracy theories by Rajapaksha, former President claiming India was responsible for his election loss.
7. Recently and in the past India has had good enough relations with Myanmar to ask them to fight militants in their territory. Currently we even have the right to cross over to Myanmar and take them down
8. Bangladesh: Visit the Bangladesh section for all kinds of conspiracy theories, the new bangla govt. has been for some reason extremely friendly towards India..
