Merica V Russia And people call it a World war lel. No one carez
UK are obliged too.
WWs come about in a domino effect, two main parties calling on allies' assistance and then so on...
No, it can't and won't happen.
Some of the major world leaders may not be the brightest sparks, but they're old enough and mature enough to understand a full-scale World War would result in at least near-total human annihilation.
I think a lot of people fail to understand how much weaponry has advanced since the first half of the 20th Century.
Oh yes, countries can declare war but it won't get far, because it won't be like WW1/2's bog standard bombs, it will be atomic bombs.
Think Hiroshima and Nagasaki but instead of just two cities in that state, the entire world and it's population ravaged in a similar, but more powerful manner. You have to remember that in WW2, only two atomic bombs were used in five years but it would be different in a WWIII scenario, as many major countries have at least a few hundred (I know for a fact that the UK has kept untold atomic bombs hidden in some air bases) and the destructive power of an atomic bomb is far more than that of a conventional bomb:
"
To take one example, if a 20 kiloton nuclear bomb (about twice as powerful as the bomb dropped on Hiroshima) was exploded on a city, the heat and blast generated would vaporise all people and buildings in the immediate area, and make a crater that might be as much as 100 metres in diameter. The wind created by the blast could be several hundred km/hr. The destruction of buildings would increase death and injury due to flying glass and other debris.The release of ionising radiation is a phenomenon unique to nuclear explosions and causes additional casualties alongside those caused by blast and thermal effects. There would be a number of deaths from radiation sickness, for which there is really no effective medical treatment.
Large amounts of earth, water and other debris in the area surrounding the explosion would be sucked up to form a "mushroom cloud" of radioactive debris. When this material returned to earth, as fallout, the effects could be spread even further, and might make the city (and an area of countryside stretching tens of kilometres downwind) uninhabitable for many weeks or even years."
And even a 20 Kt nuclear bomb is small considering the US has tested up to 15,000 kt.
I've studied WW1/2 in depth and how large powers have progressed their warfare abilities. *Certain* countries have even come across worst-case scenario of wiping out the human race.
War can happen but a full-scale World War like the previous? No, the US/UK will have to either talk down the issues or aim for a quick defeat. But since the modern world is so global-everything, the former is the most likely.
Plus, there's UNEP to consider too.
