True about the rise and fall of civilisations.Are you human or you belong to some alien nation immune to nuclear fall out.
Wishing nuclear war means death wish for almost half of the world's population, loss of 75 percent of land mass, very large chunk of ozone layer vanishing, entering in nuclear summer day and winter night and ice age, food scarcity and many more.
You thinks by sitting in UK you will remain safe and sound, then you are highly mistaken. You and any living on this earth will face the harsh reality of nuclear fallout.
This is not WW2 era, it is 2020, more than 350 - 400 nuclear missiles and bombs and self propelled shells can cause unimaginable havoc and disaster, more than a billion population will be wiped out in first days of the nuclear war, but actual calamity will start in the form nuclear fall out due to 300 to 400 nuclear and thermonuclear explosions.
Do not brag about your high IQ and good physical appearance, these are all relative terms. Remember there was a time when whole Europe was in the dark age turmoil and at that time new Muslim nation was rising and finally become a force to reckon for the west. Muslim empires became the Centre of learning. In this world some rises and some falls. None can stay in one state or position.
At present Chinese nation is rising very rapidly and days are very near when western domination will become a part of history.
Anyway, do India and Pakistan even really have nuclear capabilities? Both have only tested nuclear weapons a very small number of times, while states like China, the UK and France have tested dozens of times, and America/Russia hundreds of times. How do they know that the nuclear weapons will even work in combat?
