Kim better hope the test is successful. Otherwise, what options would President Trump have?  Let Kim develop an ICBM and take a chance it won't work?  Sacrifice a US city or cities? Or, take preemptive action and turn North Korea in to a radioactive parking lot?  The last option may be the only option open to Trump to take. Otherwise, Japan and South Korea become satellites of the Peoples Republic of China or Russia.  

Kim is playing an extremely dangerous game that could easily result in a worldwide nuclear holocaust.  Would Russia or China risk everything they have to protect North Korea?  This situation is no longer a crap shoot in Eastern Asia, but much like a spaghetti western where multiple parties are in a "Mexican Standoff" where a lot of people will end up dead, one way or another.
