It is getting real folks (N. Korea I mean)

Three articles here that address the same issue of Sec of State Tillerson rejecting talks with N. Korea and adopting a new tactic. WaPo Tillerson says all options are on the table , BBC News US Speaks of N. Korea military option, and NYT Rex Tillerson Rejects Talks . What does this mean? He** if I know. On one hand, Tillerson could be using tough talk to drive China into a more aggressive action against N. Korea. The issue there is that China has not done enough to control the Kims, probably to maintain a sphere of influence and keep Japan in check. In addition, we have been "talking" to N. Korea for 20+ years with no sustained cooperation and Kim has simply increased their nuclear capabilities. On the other hand, is Tillerson venturing into a delicate diplomatic situation with Trumpian and Exxon bravado that will pull us to the verge, or into war in Asia? (And let us remember the history of fighting in Asia.....WWII, Korea, Vietnam..... our last big success was Commodore Perry's sailing into Yedo Bay and then the Teddy Roosevelt Great White Fleet.) You decide.
