You have started a nice topic here.
Yes, to some extent you are right the Anna Hazare the Ganghi 2 in the making. Gandhiji fought for freedom with the tool of Ahimsa Non-violence, Satya Girah Hunger Strike. He was successful in getting the freedom and same proven tools are being used by Anna to make India corruption free.
Gandhiji was influence by the battle of Karbala where Imam Hussain (AS) the grandson of Prophet Mohammed (PBUH) use this tool against the tyrant rule of the then king. Imam Hussain had only 72 men with him against the large army of 1 lakh, Still he won the battle and Gandhiji said while he started his Dandi March, "I am influence by Imam Hussain (AS) who took 72 men to fight against the tyrant ruler, and here I am starting this march with 72 men only. This was the first ever move of Gandhiji against the British rule.
This is a prove fact that this will never backfire but there can be some delay.
