Will , or could Japan take action on their own , in a millitary sense ? After all it is their territorial space that was violated.Are they handicapped by America ?
What country wants foreign powers missiles flying through their air space.?
The big question is what will China do with NK,? if anything.And if they dont what are the consequences ?
The potential is NK provoking the USA And China into a confrontation,and I dont think either side wants that to happen.
All it needs is some imperfect human to make a miscalculation and all hell could break loose .
Interesting times ahead I see.
