“Russia’s thinly veiled threats to use nuclear weapons remind the world that escalation of the conflict – by accident, intention, or miscalculation – is a terrible risk. New Construction at Russia's Novaya Zemlya nuclear test site, June 22, 2023. Lop Nur nuclear test site. “The Chinese test site is different than the Russian test site,” Lewis said. Both countries keep their strategic nuclear arsenals on “hair-trigger” alert, meaning that nuclear weapons can be launched on short notice.

☆ Trinity Nuclear Test’s Fallout Reached 46 States, Canada and Mexico, Study Finds

In July 1945, as J. Robert Oppenheimer and the other researchers of the Manhattan Project prepared to test their brand-new atomic bomb in a New Mexico desert, they knew relatively little about how that mega-weapon would behave. On July 16, when the plutonium-implosion device was set off atop a hundred-foot metal tower in a test code-named “Trinity,” the resultant blast was much stronger than anticipated. The irradiated mushroom cloud also went many times higher into the atmosphere than expected: some 50,000 to 70,000 feet. A new study, released on Thursday ahead of submission to a scientific journal for peer review, shows that the cloud and its fallout went farther than anyone in the Manhattan Project had imagined in 1945. Using state-of-the-art modeling software and recently uncovered historical weather data, the study’s authors say that radioactive fallout from the Trinity test reached 46 states, Canada and Mexico within 10 days of detonation.

☆ A terrifying animation shows how 1 'tactical' nuclear weapon could trigger a US-Russia war that kills 34 million people in 5 hours

A simulation called "Plan A" produced by researchers shows how the use of one so-called tactical or low-yield nuclear weapon could lead to a terrifying worldwide conflict. In the roughly four-minute video, a Russian "nuclear warning shot" at a US-NATO coalition is followed by a tactical nuke that leads to a global nuclear war. "This project is motivated by the need to highlight the potentially catastrophic consequences of current US and Russian nuclear war plans. The risk of nuclear war has increased dramatically in the past two years," the project states on its website. The following shows how a NATO-Russia conflict involving a nuclear warning shot and the use of a tactical nuclear weapon could quickly escalate into a full-scale nuclear war.
