Explanation:

It is thus clear that the Constitution authorises the Parliament to form new states or alter the areas, boundaries or names of the existing states without their consent. In other words, the Parliament can redraw the political map of India according to its will. Hence, the territorial integrity or continued existence of any state is not guaranteed by the Constitution. Therefore, India is rightly described as ‘an indestructible union of destructible states’. The Union government can destroy the states whereas the state governments cannot destroy the Union. In USA, on the other hand, the territorial integrity or continued existence of a state is guaranteed by the Constitution. The American Federal government cannot form new states or alter the borders of existing states without the consent of the states concerned. That is why the USA is described as ‘an indestructible union of indestructible states'.
