No, man you don't get it. $400,000 worth of gold is NOT going to be what pays for a hydrogen bomb. Take a look at the money Jong-Un spends on luxury items each year.
Kim Jong-un's unbelievable life of luxury
Just one of the items:
IMPORTED LIQUOR
While local alcohol is cheap and readily available, it clearly isn’t to Kim’s taste. Instead, he reportedly spends an average $30 million (£21M) each year on importing liquors into the country for his elite circles. His favorites are whisky and cognac, but not just any brands. He prefers the more expensive kinds such as Hennessy which can cost up to $2,145 (£1,500) for the best bottle.
That's $30 MILLION a year on liquor. Now you think $400,000 in gold makes a difference?
