I think we are doing the right thing given where we are now-- keeping pressure on NK. We have a good redline--  which Kim gave us-- his firing Missiles at an area off of Guam. If he does so, Trump is clear that we will strike and the message is clear from all on our side. There is some reported intelligence that this pressure is causing some internal issues in NK which could result in changes or internal moves against Kim. Like a Chess match, we have seen generals (they sent the message) have a relatively "weak" position-- shooting missiles off of Guam with no threat of nuclear. This lets Trump respond after what they and not have to back up his words now. This gives at least a week for anyone in North Korea with a chance to takeout or contain Kim to do so (if there is truth to intelligence of sudden instability in N. Korea) or we either counter an attack on Guam after it happens (per Trump's promise) or we are in position of standing up while NK backed down.
