The National Post reports in its Saturday edition that the ripple effect of the U.S.-Israeli war against Iran has moved beyond oil markets and has now reached consumer goods such as Diet Coke. The Post's Laura Brehaut writes that Diet Coke is only sold in cans in India. Some orders are unfulfilled due to a can shortage linked to the Iran war disrupting aluminum supplies. The Persian Gulf region produces about 9 per cent of the world's aluminum. The cans are disappearing from shelves as "Diet Coke parties" pop up across the country. Revellers are paying $10 (U.S.) to $16 (U.S.) entry fees for the pleasure of partaking in Diet Coke-centric drinks and activities. Marketing executive Ishika Gupta was reportedly the first to throw a "Diet Coke party" on April 26 in New Delhi. He said it started as a joke. "I thought only me and two of my friends would show up." The alcohol-free event sold out. Roughly 150 genzers showed up wearing Coke-themed outfits to dance and party. Mr. Gupta said: "We had a cocktail menu, which we call Coke-tails. The idea was to bring fans together." Mr. Gupta is a self-professed "big Diet Coke fan" who reportedly started an Instagram account devoted to the drink a month before the Iran war began.
