My Dear Shiva, You present good hopes. …But I do not think a WW at this stage would be the end of the Earth. …Dog putin, if he starts it, would ally with china, n korea, and possibly venezuela. On the other side would be the West which is Bigger than NATO (non NATO members would be joining in).
I do not think most of Africa or S America would be involved (except for crackpots).
china would use the opportunity to nuke India, as would India into Pakistan.
For all that, LARGE tracts would be UN-involved, as I see it. Also, even the combined lot of nuc warheads would not be able to Disintegrate the earth.
NO doubt it would be a Horror.
Warning! VERY Horrific pictures.
But FOND HOPES will not prevent it.
Let us Pray Good sense prevails. Om Shanti.
