The worst war in global history was Cross War yet cross-sections survived.
What are you talking about?!!😨
---We are in an age of press-button war.
----we are in an age of more advanced annihilating destructive weapons than the cross war age.
--were all the amassed weapons positioned at one place on the earth and detonated at one time the Earth would be dislocated from its imaginary axis of rotation, What powerful those weapons of today are!!!
----The nuke weapons leftovers would remain on Earth surface for thousands years making the would battle field inhabitable for such years leading Europeans influx to the areas which would be safe to live, those areas; viz Africa, Latin America, some part of Asia, Australia etc.
----Out of influx; there would be frictions between native inhabitants and the war refugees from wartorn areas leading to another internal strife.
----There would emerge malpractices , vices etc, in societies due to raging life hardships created by the war.
----Many people would die from diseases due inadequacy of medicines as big pharmas would not be producing medicines etc.
--- Many sectors of productions would stop due to lack of raw materials etc, there would be no easy transportation, no easy farming to produce foods and transportation of which would be difficulty.
-----Many death caused by food scarcity.
With all that written, never can a sane person seldom think about such tragic war to occur in our times.
