Why shouldn't NK test missiles as much as they like? The US is claiming that right for themselves and they even violate treaties just to test missiles and even nukes (as do other nations like France but that's not the point since the French don't fantasize about shooting down other countries' missiles). Oh well, the double standards don't surprise me anymore. The whole foreign policy of the US reeks of double standards and hypocrisy (Guantanamo FTW!).
