Haha, the arrogance is astounding. Experts on international affairs wouldn't make claims like that
I could go on, but this is literally the first page of googling for "nuclear attack shipping container".
Even suggesting that North Korea is a "don't-give-a-shit" state is laughable.
South Korea is the one with the world's 8th highest household income.
North Korea is the one with the nuclear programme where several million people starved to death in the 1990s and many are now are forced to eat grass to survive.
You really shouldn't base your beliefs on things you're just making up.
Similarly, you really shouldn't base your beliefs on your current love of the armed forces.
Clearly neither of us are experts on international affairs. But it's not unreasonable to point out that most of the complexity required by today's nuclear powers is because they want things like the ability to launch strikes from submarines or deliver an overwhelming response to someone with a similar level of technology.
That only works if everyone else plays the same game as you do. 9/11 has cost the US tens of trillions of dollars and two decades of conflict using nothing more than a few dozen fanatics and some planes.
