Do you think N Korea will engage in any thing more serious than a war of words

Obviously N Korea wants sanctions lifted

What might they try  to have sanctions lifted

America removves anybody that tests positive from military action

I doubt N Korea cares the same about it's military

N Korea may think the USA military is weakened and now is as good a time as any to engage in aggressive offensive actions Test the DMZ and then a bit more in small increments of advancing troop manouvers, might be one such action.

That sister seems to be gung ho for some thing
