History is very important. What you are stating is theory. Everyone would like it that way, but the practice over the ages is very different.
Knowing ones history is extremely important. We were taught in schools that Moghul rulers were so considerate and peace loving bla bla. That was medeival times i.e. brutal, barbaric etc. Todays world with internet, newspapers, TVs etc. clearly shows that brulality and barbaric behavior and extreme intolerance exists all over the islamic world.
It is hard to believe that peace and quiet existed during Moghul rule.
Be realistic. Be peace loving but carry a big stick as a famous leader once said. India should have a very very strong deterrent and then preach all the peace it wants. Look around the world and see what the countries are doing, saying etc. over the last 50 years.Every country says that it loves peace and bla bla bla. Each has a strategy and its vision of the world.
India has had enough of the Ghori, Ghazni and the lousy British. Enough. No more such bull. Talk peace but kick ass when required. Got it?
