Pune, Dec 24: Prime Minister Narendra Modi on Saturday said that if the evils of corruption and black money had been tackled by the previous governments, he would not have been forced to take a tough decision like demonetisation. “If the ills of the country had been tackled on time in the past 40 years, I would not have resorted to such a harsh decision.”Those who failed to take the decision have pushed the country to grave peril — I have saved the country, as I had promised to do,” Modi said at a public rally here after inaugurating the Rs 11,420-crore Pune Metro project. Continuing with his defence of demonetisation, he again warned the corrupt and black money hoarders to come clean or face the consequences. Reiterating his earlier statements in Mumbai — to continue the war against corruption, black money hoarders, terror and Maoists until achieving victory — Modi exhorted those with undeclared money to reveal their untaxed wealth and “sleep peacefully”. “If they don’t declare, then at least I will not sleep,” he warned, vowing to give justice to the 125 crore people of the country, who have suffered over 70 years because of a handful of corrupt elements.
