In exchange for legal annexation. If there is one thing bothering the island nation of the Maldives...it is that they will cease to exist for longer than a few decades, due to rising sea levels thanks to global climate change. India should play on this fear, and offer to build massive dykes around the archipelago to keep the water out (as the netherlands have been doing for centuries) under the condition of autonomy under the Indian Union, like J&K, Sikkim etc. If need be, we can eventually start slowly pulling the rug of autonomy from out under their feet (like we have been doing in J&K since accession). Do you think the Maldivians value their sovereignty more, or their very homeland's existence?
