Differentiation

 Most of us have studied basics of Calculus and know too well that integration is more difficult than differentiation. 

In order to integrate, you have to understand the principles of differentiation too well. 

And also many internet teachers teach us to divide tasks into small manageable tasks. Divide and conquer. 

So it is in politics too. Integration is much more difficult and is less vote fetching. Where as differentiation is easier. And is more popular. So leaders world over, use differentiation - division to come to power and stay in power. Because united people are stronger and so can't be ruled efficiently.

What they don't realize until its too late is that the ghosts of their past will catch up with them and hound them. Like what's currently happening to our neighbor down south. Like had happened to our ex prime minister.
