He made no reference to nuclear, just armaments. Lots of folk could have foreseen that. But really this is just the difference between prophet based religions and the rest of us. In prophet based religions, almost by definition, the prophet holds all the wisdom, while the rest of us are fools. In non-prophet based religion, wisdom is spread around a little more. Also has to do with where God is. Again, very different paradigms.
India's nuclear stuff is just to balance Pakistan's, which is a very real danger, as is North Korea. It's the nutcases we all have to watch out for.
Arguably Baha'u'llah did make reference to nuclear weapons:
“Strange and astonishing things exist in the earth but they are hidden from the minds and the understanding of men. These things are capable of changing the whole atmosphere of the earth and their contamination would prove lethal.”
Baha’u’llah, The Tablets of Paradise (circa 1891)
Again in regards to the need for international cooperation:
“The time must come when the imperative necessity for the holding of a vast, an all-embracing assemblage of men will be universally realized. The rulers and kings of the earth must needs attend it, and, participating in its deliberations, must consider such ways and means as will lay the foundations of the world’s Great Peace amongst men.”
Baha’u’llah, Gleanings from the Writings of Baha’u’llah (circa 1881)
The only reason we have some semblence of international cooperation is because its necessity was so clearly apparent in the aftermath of both WWI and WWII. Inhabitants of every country regards members of every other country as 'nutters', and that is the justification for the proliferation of nuclear weapons. North Korea regards the West with suspicion and derision as does Iran. Their argument becomes, if this country can have nuclear weapons, why can't we. Unfortunately this approach just heightens the risk of a catastrophe of monumental proportions for us all.
The Abrahamic tradtions date back thousands of years as with Hindu traditions. The Abrahamic Faiths have inspired great and profound intellectual developments throughout history. It has been the West that has promoted social and technological advances that have positivly shaped todays world. India appears to have been slow to adapt to the modern era and a fairer distribution of the benefits of modernism has often been hindered, not helped by Hindu traditions. I don't think your analysis holds up.
