A UNILATERAL STRIKE BY NORTH KOREA ON ANYONE WOULD BE SUICIDE
On the Phillipines.
Even on China.
A unilateral strike by North Korea on anyone would be suicide.
But when there's hundreds of US bases surrounding you, and they've just killed a million, and overthrown all those leaders in Iraq, Libya and tried it but failed so bombed Syria, then you're bound to be a bit, you know, gobby, and want some form of protection.
I can't see Kim ordering a first strike.
But after what he did in Syria, I can see Trump ordering one.
