As in 1950, the Norks see a US Military weakened by years of budget cuts . They see a military bloated at the top with garrison officers and generals unfit for real combat. Grandfather Kim was correct in this perception.
The current Kim misinterprets not only history but the current President. The US Navy can destroy all of North Korea in a matter of hours. The recent defector probably brings the message that the troops are not in agreement with their commanders. They prefer the good life in Seoul rather than starvation
Fatboy was educated in Switzerland, IIRC.
He is either totally ignorant, delusional or both.................
The US Navy? Try one B-1 Bomber.
