Operation OperaOperation Opera ( מִבְצָע אוֹפֵּרָה), also known as Operation Babylon, was a surprise airstrike conducted by the Israeli Air Force on 7 June 1981, which destroyed an unfinished Iraqi nuclear reactor located southeast of Baghdad, Iraq. The Israeli operation came after Iran's partially successful Operation Scorch Sword had caused minor damage to the same nuclear facility a year prior, with the damage having been subsequently repaired by French technicians.
Manhattan ProjectThe Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with support from the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. The nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the bombs.
North Korea and weapons of mass destructionNorth Korea has a military nuclear weapons program and, as of early 2020, is estimated to have an arsenal of approximately 30 to 40 nuclear weapons and sufficient production of fissile material for six to seven nuclear weapons per year. North Korea has also stockpiled a significant quantity of chemical and biological weapons. In 2003, North Korea withdrew from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Since 2006, the country has been conducting a series of six nuclear tests at increasing levels of expertise, prompting the imposition of sanctions.
