Technologically, the ICBM has sent North Korea's progress graph skywards and promises bigger, better and faster with the probability of a nuclear warhead to suit.
Politically, such a development could alter the balance of power in a region where things are already fragile.
It constitutes a threat to a number of nations, including South Korea and the US, both, along with Japan, having said they will not accept a nuclear-armed North Korea.
What does that mean, "will not accept"?
South Korea has its own military, as well as 28,000 US troops parked on its soil, and Japan's no slug when it comes to defence, so what exactly do they mean to do to counteract this obvious and intentional threat?
Rattle their sabres? Negotiate? International sanctions? Diplomatic pressure? Something more tangible and threatening?
Kim Jong Un probably feels he's got a good chance of winning if it came to war, and I don't think he'll back down to empty gestures.
Are we safe in the South Pacific? Let's hope so, but I don't like where this arms race is headed.
