The United Nations’ Security Council, though initially formed to keep the peace between the post WW2 Great Powers, is today the hub of global peace and security in wider terms.

India, along with other rising great powers, has declared its ambitions for a permanent seat in a reformed UNSC. However, the unfolding humanitarian crisis in Sri Lanka is revealing the limits of Delhi’s ability to both be decisive and to act on matters at the core of the UNSC’s agenda.
