So, the North Korean missile test failed. I am not that surprised as I feel the USA had something to do with this. Of course, I may be totally wrong, and indeed I hope I am.
The Trump administration would be unable "neutralise" the North Korean nuclear threat without unpredictable consequences, but the USA Secret Service was probably in a position to do something to put a "spanner in the works". Of course, the USA never uses such underhand techniques.
