It is remarkable that Alexander the great was able to conquer as much of the world as he did, with the military power of Macedonia, a relatively small country, and using the relatively primitive technology of the day. If your best method of transportation is horseback, the world is extremely large. It takes months to travel on horseback a distance that can be traveled by plane in a few hours. Messages had to be sent by courier, also taking months, rather than by instantaneous modern methods. This makes it ridiculously difficult to coordinate the administration or military maneuvers of a large empire.
Ancient Greece itself had no real weakness, since each individual city-states makes up for the weakness of another. For example, Spartan had a horrible political system, with oligarchy, monarchy, and democracy all together, yet Athens' democracy more than makes up for Spartan's political weakness. On the other hand, Spartan military make the whole Greece military seem stronger.
The countries that are trying to unite will be able to commute with each other.
The Indians did not unite and attack the british because the british did not give them a chance to unite and attack.
