CONFLICT between nations is nothing new. Mankind have fought and lost wars for as long as history has been recorded and recent advances in science and technology make the threat of an attack, anywhere in the world, a real and terrifying prospect.

Whether it’s nuclear, chemical or any other form of military response, history shows no one is safe from the devastation of war.

With ongoing conflict in Syria and US President, Donald Trump’s response to the latest chemical attacks, the likelihood of an attack on a highly populated city is a plausible nightmare.

Scientists from Virginia Polytechnic Institute and State University have created simulations of a potential outcome if an attack did occur, and found the best course of action for people was to take shelter first and then take steps to escape afterwards.

Those who tried to seek out family members and “aid and assist” others were more likely to die.

In the study, it showed some people would look out for family, while others wold panic and run blindly away.

When humans carried out “shelter-seeking, evacuation, healthcare-seeking, and worry combined,” they were more likely to survive.

The simulation, which was first revealed by Science Magazine, shows that venturing away from a safe place leaves civilians subjected to a higher dose of radiation, which would likely prove fatal.

With President Trump’s consistent tweets threatening action against Russia and North Korea in a game of who has the bigger artillery, a dystopian future seems more and more possible.

Last month researchers created an interactive map that revealed the terrifying scope of a nuclear blast for any given area.

The map shows the extent of the fireball, radiation, shockwave, and heat spawned by different weapons, from the 15 KT ‘Little Boy’ dropped on Hiroshima to the largest weapon in the USSR’s arsenal, the 50,000 KT Tsar Bomba.

For example, if North Korea dropped the Hwasong-14, a 150 KT yield nuclear weapon on Sydney’s CBD, there would be more than 77,000 fatalities and 156,000 injured. The radiation from the blast would exceed 12 square kilometres and go further depending on wind patterns.

If Vladimir Putin dropped a 50,000 KT Tsar Bomba (Reportedly the biggest in his arsenal) on Sydney, there would be 1,513,303 fatalities, 1,111,725 injuries and radiation exceeding 80 square kilometres.

If the Aussies pissed off the US and Trump attacked us, it would most likely be with the 300KT W-87, which would kill an estimated 114,374 Sydneysiders, injure more than 227,000 and cause radiation exceeding 15 square kilometres on initial impact.

While scary to think about, it’s an important thing to get your head around in Trump’s 2018. Without coming off as alarmist we should understand the exact magnitude of a nuclear blast and how damaging it can potentially be.
