If a nuclear weapon were to detonate in a big metropolis, the explosion core would be hotter than the sun's surface, tornado-force winds would spread the fires, and a million or more people would perish. Survivors would be without power, transportation, or phones and hospitals would be overburdened if they were still standing according to USA Wire news. Nearly 16,000 nuclear weapons are held by nine countries: China, India, Israel, France, North Korea, Russia, the United Kingdom, and the United States. That would be enough to wipe the earth clean hundreds of times over.
Even though the Cold War ended more than two decades ago, the existence of thousands of nuclear weapons continues to represent a severe worldwide threat. Although the chances of a nuclear war between the US and Russia have lessened, the continuous presence of massive stockpiles makes the deployment of nuclear weapons by accident or unauthorized means a constant threat. Many countries with lesser nuclear arsenals, such as India and Pakistan, are involved in regional disputes, raising the prospect of regional nuclear war. North Korea obtained nuclear weapons illegally, while other nations, such as Syria, have broken their nuclear safeguards obligations and are accused of secretly developing nuclear weapons capability as reported on USA Wire.
United States and Russia
The United States and Russia control the great bulk of nuclear weapons in the globe. Former Cold War adversaries own 93 percent of the global stockpile. And, over two decades after the end of the Cold War, the two countries have nearly 2,000 nuclear weapons on high alert, ready to be launched against each other at any time. As a result, both countries are far too susceptible to a nuclear mishap, a miscalculation, or even a cyber assault.
Terrorists are known to be on the lookout for nuclear weapons. More than 1,800 metric tons of weapons-usable nuclear materials, including highly enriched uranium (HEU) and plutonium, are currently housed in hundreds of locations across 25 nations, some of which are poorly secured. Terrorists won't hunt for the largest stockpiles of nuclear materials to create a bomb; instead, they'll look for the most vulnerable nuclear materials. As a result, global nuclear security is only as strong as its weakest link.
Systems of command and control aren't ideal. People make errors. Sabotage is a possibility. Systems and technology both have weaknesses. The risk of an unauthorized launch or even a permitted launch without adequate planning is simply too great. Nuclear technology and the know-how to make a bomb are no longer a state-owned monopoly. The fear of cyber-terrorism is real, and specialists are working feverishly to stay on top of cyber weaknesses that could be exploited by hackers to cause havoc.
Regional rivalries in the Middle East, Northeast Asia, South Asia, and other parts of the world represent clear and present nuclear threats to global security. These rivalries increase the danger of intentional use of a nuclear weapon, with the implications of a regional nuclear exchange reverberating around the world. It's not all doom and gloom. Ukraine, Belarus, and Kazakhstan surrendered the weapons they inherited when the Soviet Union disintegrated as per republican news sources. South Africa disarmed its nuclear weapons on its own accord.
Diplomacy and collaboration
Through diplomacy and collaboration, the number of weapons in the United States and Russia has decreased dramatically since the Cold War's peak. More than 50 countries have taken part in Nuclear Security Summits at the head of the state level to combat nuclear terrorism. Recently, world powers and Iran achieved an agreement to adopt a strict monitoring and verification framework in order to prevent Iran from developing a nuclear weapon. Despite improvements, the nuclear threat, which was previously symbolized by duck-and-cover drills, is more sophisticated and unpredictable than ever.
