Aircraft carriers can let you fly fighters from the ship while at sea anywhere in the world. You might have seen one in Pearl Harbour movie. What it does is let the enemies know that when needed, we can reach you, even if you are on the other side of the globe.
All seems good, we have a grand old ship that can carry planes, India rules.
Only, we don't have any enemies except at our borders. And these enemies can be bombed by flying fighters from our own land. But we don't really do anything.
If we can't take military action against enemies that exist on our borders, what is the point of having a ship that can be used to bomb countries on the other side of globe?
