Yeah! Does the length of time have to decide the importance of a tenure in history? Sometimes few moments are enough to leave a scar on history, eg., Jallianwalah Bagh massacre in 1919, Bhopal gas leak 1984, Babri mosque demolition 1992 or the 1993 Mumbai blasts, the tsunami, etc. People will seldom forget a Sanjay Gandhi or a Jagdish Tytler or a Bal Thackeray/Raj Thackeray.
