Julian Lennon thinks the world is the "worst" he's lived in now because of the "veiled threats from Russia" and North Korea's missile tests. The 'Saltwater' singer - who is the son of the late John and Cynthia Lennon - doesn't understand why people "do not want peace" and despite all the conflict going on around the globe, he's still trying to stay "hopeful" for the future. Asked if he finds it hard to summon optimism, he told Independent.
