Should the US and Russia resume nuclear testing?
The answer to that question must be a resounding “No.” Yet US President Donald Trump and Russian President Vladimir Putin, eager to project strength, have raised fears that they might be moving to revive the dangerous practice. While the significance of testing nuclear weapons dwindled more than 60 years ago, the terrifying circumstances that brought that era to a close should remain top of mind, reminding leaders why using nuclear testing to gain a strategic advantage is a terrible idea.
Thanks to Hollywood, many audiences know something about the dawn of the nuclear age. Led by physicist Robert Oppenheimer, a crack team of eccentric geniuses housed at Los Alamos, New Mexico, built and tested the first atomic bomb in 1945. It led Oppenheimer to recall a line from the Hindu sacred text, the Bhagavad Gita: “Now I am become death, the destroyer of worlds.”

Although the atomic scientists who followed Oppenheimer lacked his literary sensibilities, they took world-destroying quite seriously. Teams in the US and the Soviet Union competed to build and test ever-larger bombs in a blatantly obvious effort at intimidating the other side.
The US went first, forcing the indigenous people of Bikini Atoll to relocate so that it could detonate bombs in the Marshall Islands in 1946. Radioactive debris rained down on the sailors sent to watch the tests. They absorbed dangerous doses of radiation, as did many of the native islanders living in the area, inaugurating a multigenerational legacy of cancers and birth defects.
NUCLEAR RACE
Nevada, where the US military began above-ground tests in 1951, was no better. There, too, the federal government confiscated land owned by indigenous peoples and placed soldiers far too close to the detonation sites. In subsequent decades, their bodies would be plagued by cancers and other maladies born of their fateful exposure.
Back in the Marshall Islands, the US began testing a new generation of nuclear weapons that used conventional fission bombs to detonate a much larger, “fusion,” or hydrogen bomb. These experiments went terribly awry during the infamous Castle Bravo test of 1954.
The bomb in question was supposed to generate the equivalent of 5 to 6 megatonnes of TNT. However, hanks to some serious miscalculations, the explosion clocked in at 15 megatonnes, or 1,000 times the size of the bomb dropped on Hiroshima, Japan. The explosion sucked up 10 million tonnes of sand and pulverized coral, creating a massive fallout cloud that fell on islanders, US military personnel and even Japanese fishing vessels 129km east of the test site.
This was what historian Alex Wellerstein has described as “the greatest single radiological disaster in American history.” It also holds the record of being the biggest nuclear test ever conducted by the US. It might have remained the biggest test ever had it not been for the Soviet Union.
After World War II, the communist nation worked desperately to build and test its own bomb, terrified of what might happen if it failed. Indeed, a Russian nuclear scientist who attended the Bikini test in 1946 claimed that the purpose of the demonstration had been “to frighten the Soviets.”
Thanks to atomic spy Klaus Fuchs, the Soviets managed to detonate their first atomic weapon in 1949. Still, they spent much of the next decade playing catch-up, countering progressively larger tests with their own demonstrations. Former Soviet premier Nikita Khrushchev, eager to pull ahead, approved a top-secret project to build the biggest nuclear weapon in human history. It was known as “Kuzma’s mother,” an allusion to a Russian idiom that basically means: “We’ll show you.”
When completed in 1961, “Kuzma’s mother” — also known as the Tsar Bomba or the “King of Bombs” — was the size of a school bus and weighed 25 tonnes. It was too big to fit into any of the Soviet bomber aircraft, so the military removed the bomb bay doors on a Tupolev TU-95 and strapped it to the bottom of the plane.
MASSIVE BLAST
On Oct. 31, 1961, the TU-95 left a Russian airfield bound for Novaya Zemlya, a collection of islands above the Arctic Circle; a separate plane containing a film crew accompanied it. They departed not knowing if they would return home: Authorities had given the planes a 50/50 chance of surviving the shock wave.
When they reached the target location, the bomber dropped its lethal package. The bomb, fitted with a parachute to slow its descent and give the planes time to escape, floated downward until it reached 4,000m before exploding.
The blast, which could be seen more than 1,000km away, registered at 57 megatonnes, 10 times more powerful than all the bombs and ordnance used in World War II. Had any human been within 100km of the epicenter (there were not any), they would have been immediately vaporized or have sustained third-degree burns. The shock wave shattered windows 901km away.
The test inflamed Cold War tensions, and a year later, the world came dangerously close to complete annihilation during the Cuban Missile Crisis. In its wake, saner heads began to prevail, and the US and Soviet Union signed the Partial Nuclear Test Ban Treaty in 1963, which moved nuclear testing underground, where it became less of a provocation. A complete test ban followed 30 years later, aided by that computer modeling has effectively made nuclear testing obsolete.
Trump and Putin now seem inclined to take us back to the bad old days of nuclear testing out of some misguided belief that it is an effective way to assert dominance over adversaries. History already shows how that story ends.

There is a modern roadway stretching from central Hargeisa, the capital of Somaliland in the Horn of Africa, to the partially recognized state’s Egal International Airport. Emblazoned on a gold plaque marking the road’s inauguration in July last year, just below the flags of Somaliland and the Republic of China (ROC), is the road’s official name: “Taiwan Avenue.” The first phase of construction of the upgraded road, with new sidewalks and a modern drainage system to reduce flooding, was 70 percent funded by Taipei, which contributed US$1.85 million. That is a relatively modest sum for the effect on international perception, and
When former president Tsai Ing-wen (蔡英文) first took office in 2016, she set ambitious goals for remaking the energy mix in Taiwan. At the core of this effort was a significant expansion of the percentage of renewable energy generated to keep pace with growing domestic and global demands to reduce emissions. This effort met with broad bipartisan support as all three major parties placed expanding renewable energy at the center of their energy platforms. However, over the past several years partisanship has become a major headwind in realizing a set of energy goals that all three parties profess to want. Tsai
An elderly mother and her daughter were found dead in Kaohsiung after having not been seen for several days, discovered only when a foul odor began to spread and drew neighbors’ attention. There have been many similar cases, but it is particularly troubling that some of the victims were excluded from the social welfare safety net because they did not meet eligibility criteria. According to media reports, the middle-aged daughter had sought help from the local borough warden. Although the warden did step in, many services were unavailable without out-of-pocket payments due to issues with eligibility, leaving the warden’s hands
At the end of last year, a diplomatic development with consequences reaching well beyond the regional level emerged. Israeli Prime Minister Benjamin Netanyahu declared Israel’s recognition of Somaliland as a sovereign state, paving the way for political, economic and strategic cooperation with the African nation. The diplomatic breakthrough yields, above all, substantial and tangible benefits for the two countries, enhancing Somaliland’s international posture, with a state prepared to champion its bid for broader legitimacy. With Israel’s support, Somaliland might also benefit from the expertise of Israeli companies in fields such as mineral exploration and water management, as underscored by Israeli Minister of
