I'm guessing I'm not the only one feeling concerned about North Korea's ambitious armaments programme and the likelihood of its success.
This week they sent a high-powered phallic symbol on a 40-minute flight more than 2700 kilometres above Earth and into the Sea of Japan (Koreans call it the East Sea).
With that sort of distance capability, fired at a lower trajectory, this missile could reach mainland US, making it a genuine intercontinental ballistic missile (ICBM) and real reason for concern.
While North Korea's glorious leader, Kim Jong Un, might be a few sandwiches short of a Western picnic, his scientists and military men are not.
They are smart people who have been given unlimited resources to come up with the required goods, and it is in their best interests to do so.
