They have been firing short range missiles, of which they have plenty, most of them, along with thousands of artillery, are aimed at Seoul.They are not "running out of good missiles". The ICBM they are apparently getting ready to fire is a long range missile capable of reaching Japan if they want to fire it off that direction and capable also of carrying a nuke if the nuke is small enough(size and weight wise)to lift. They are building those in Korea and they are bringing this latest one from the same place they brought the first ICBM they fired on April 5.
“The ICBM they are apparently getting ready to fire is a long range missile capable of reaching Japan”
I thought the other missile they recently launched went over Japan and landed in Pacific? Anyway, the biggest concern with an ICBM is its ability to reach western US, no? I mean, I like the Japanese people and everything, but Americans have a bad habit of not tending to threats until we are in the cross-hairs.
