milima haikutani, lakini binadamu, hukutana
Mountains don't meet, but people do.
When you speak a foreign language, just use the words you know and pronounce them well, and others will understand.
how much does it cost to build an atomic bomb (U-235) from scratch?
The minimum critical mass is 15 kg.
Using the above as a shortcut, 1 g of 93% enriched uranium costs $6,690.
(15,000 g)*$6,690 = $100,350,000
The other costs of building the bomb are negligible in comparison. From this I can conclude that any country that can scrape together a few hundred million dollars can make a nuclear weapon.
There are about 87 countries which spend at least $1 billion per year on their military. Thus, many countries could afford nuclear weapons but choose not to build them. This estimate checks out because Pakistan's annual military is about $7.6 billion and they are a nuclear power. North Korea is also a nuclear power, and they spend about $4,7 billion per year on their military.
