India will never break.
Pakistan will break, UK will break, China will break, and Saudi Arabia will break (into Hijaz and Najd) but India will not.
Please watch Ajit Doval's video on state disintegration - he is well aware of the internal and external threats to the country.
India is waking up, and the Jaichand Forces (who have been ruling for 70 years) are resisting that awakening. We have been around for thousands of years as a civilization - no other has endured for this long. The Egyptians are replaced, the Greeks and the Romans are long gone, Persia has fallen under a dark shadow for 1500 years, and China has capitulated to communism. They only exist as political entities, not as civilizations. The body remains as a shell, but the soul has long departed.
The four corners of India that Shankaracharya blessed are a part of an identity that will not go away. India might bend and shake and get pushed into a corner, but it will not be balkanized and fractured.
India is held together by very old and very strong forces that the Western or the Eastern barbarians are incapable of either understanding or undoing, and will endure far after they have all been tossed into the dust-bins of history.
