Basic Principles of Politics

I am surprised to see that our politicians have forgotten  basic and natural principles of politics .Firstly,it is the word- impossible. Have you forgotten that in politics ,nothing is impossible ?. Our own history is in front of us.What was impossible -all became possible, and then again you are saying for any action-it is impossible.It  is advisable to the politicians for kindly correcting  this concept which may put them in a danger and difficult position.
Secondly,anything or event in the history does not mean that that is blocked for ever ,and will not occur again.You also have realized this fact  in our own country that history repeats. Time we do not know, but it repeats.
These two important principles of politics must not be overruled-it is universal truth.
