the concept of a threat to test a weapon system strikes me as a little funny. "get back," says north korea nervously, "take another step and we'll run a test to see if this weapon that i have actually works!"
i get where this is coming from. whenever a country like north korea successfully tests a new missile, the world reacts. that reaction is real even if the test itself is just a test. but it's funny that NoKo would use the disruptive nature of a successful missile test as the threat. they're not threatening to shoot anyone with the missile. they're threatening to show that they have an intercontinental missile, releasing knowledge upon the world that will cause a freakout that will disrupt things internationally.
the disruption really wouldn't be because of the test. it would be because the world would know what NoKo has. but isn't knowledge better than ignorance? i mean, either NoKo has a working ICBM system or they don't. isn't it worse not to know their capability? shouldn't we let just them test?
