The first response of both the house and senate of USA together that has been made apparently after the North Korea nuclear test of 6 January 2016.

U.S. Senate approves sanctions against North Korea after rocket launch
But there is not much other to the above actions on North Korea.
South Korea has said they would stop doing trade but it makes no difference and might hurt South Korea more because of the cheap labour. Japan is saying the same but it is bread crumbs and PRC and North Korea would have calculated these in before anyway. PRC is still doing and supporting North Korea.
If the above is the only measure the international community can measure up to with North Korea - more reason for India to test. I am sure there has to be a t minus time that is in our calculations.
The USA is now authorised by its own laws to go and tell PRC that they have to punish North Korea.
The UNSC has
USA and South Korea, Japan resolution to be drafted.
The South Korea, Japan, Taiwan and others are looking at the no response of USA and being played by PRC.
One can add to this the ASEAN Region and others.
A India nuclear test brings away many important positive takeaways for many important stakeholders mentioned above to a net benefit for all. One cannot accept such behavior by North Korea to be the norm and simply dealt with like it is acceptable like it is. A India nuclear test makes things serious and also brings in more sensible discussions on how to deal with parameters. Like India was the big and sensible party earlier with Pakistan (a unstable party) i am sure India would be kind for the peaceful and positive development of the world. The T minus time is approaching fast. If UNSC resolution is done before and with PRC veto that supersedes and allows for earlier ignition.
