Er... are you on their side?
Let's paint a scenario just for you...
America is the biggest kid in the playground. It has access to ALL THE TOYS - and it has the resources to make more. REALISTICALLY, you'd have to be extremely brave or eff'ing insane to slam the good old US of A, because it would only take a teeny-weeny, itty-bitty, tiny fraction of those resources to completely, utterly, absolutely ANNIHILATE you and the shadow of you from the face of this Earth.
North Korea has what? I heard earlier that they've sold their entire silver reserves to China, coz they need the money. NOT gold - SILVER. I read that the people of NK are starving, but I reckon the millions made from that silver sale will go, not to feeding the starving nation and stabilising the country, but to propping up the position of the power-elite and making fancy hats for the military.
Let's say that I, and all of my relatives, had gone out of our way, over decades, to pee-off the people in my homeland. The ONLY thing standing between me as Great Dictator and a very long, slow, drawn-out death, are my 'friends' in the military (but they secretly hate me too).
So long as the cash keeps on a comin', the military are happy.
So long as I buy them an occasional new toy - they're overjoyed.
Meanwhile, the sea is coming in, and the big sand-castle that this dictator is calling out from is crumbling underfoot.
How long do you think this dictator will be able to maintain his position?
