US officials puzzled by lack of North Korean missile tests
Officials caution all of this could change at any time and Kim could resume aggressive weapons testing — but that would also pose the question as to why he resumed.
One of biggest worries for the US military is that the North Korean regime might live up to its threat of conducting an atmospheric nuclear test. Officials point out the regime has a track record of following through on its threats on weapons testing.
At the moment US intelligence suggests North Korea’s longstanding underground nuclear test site at Punggye-ri has been damaged by underground seismic activity and may be unusable in certain sections. If the regime turned to above ground testing, officials say it raises the prospect of a test looking like a potential attack, especially if Kim conducts the test using a missile with a warhead.
