Nuclear weapons are a deadly reminder of countries’ inability to solve problems through dialogue and collaboration. These weapons offer false promises of security and deterrence while guaranteeing only destruction, death, and endless brinksmanship. The terrifying lessons from Hiroshima and Nagasaki are fading from memory, but the fear is still there. The world cannot forget the drastic event and its causalities, which took the lives of thousands of human beings. But unfortunately, we are living in a world with more than 13,000 nuclear weapons still held across the globe. The once unthinkable prospect of nuclear conflict is now back within the realm of possibility. The world is need to eliminate the nuclear weapons for the safety and well-being of humankind. For this purpose, the Treaty on the Prohibition of nuclear weapons is an important step towards the common aspiration of a world without nuclear weapons. It prohibits a full range of nuclear-weapon-related activities, such as undertaking to develop, test, produce, manufacture, acquire, or stockpile nuclear weapons, or other nuclear explosive devices. The treaty was adopted in July 2017 and entered into force in January 2021. It has been signed by 86 countries and ratified by 65. During the meeting in Vienna regarding the elimination of nuclear weapons, several decisions were made to help in cement the Treaty’s position as an essential element of global disarmament and non-proliferation efforts. Meanwhile, we can eliminate this scourge and get back to the business of building a better, more peaceful and trusting world for all only by joining in solidarity with the treaty. In a world rife with geopolitical tensions and mistrust, this is a recipe for annihilation. We cannot allow the nuclear weapons wielded by a handful of States to jeopardize all life on our planet. We must stop knocking at doomsday’s door.
