- Japan and South Korea are the main countries in harm's way because of North Korea and China. Besides, the U.S. Armed Forces are overstretched as is.
- Aspiring dictator Tr**p is allied with China and has praised Kim Jong-Un, and Tr**p is also allied with Russia. Besides, as I've said before, Tr**p plays nobody's puppet. Thus, Tr**p is trying to cover his own trail with his bluster and put the United States along with Japan and South Korea in harm's way.
- Tr**p is, at the least, no different than Kim Jong-Un, anyway; and, at the most, worse than Kim-Jong Un—do I or others need to rehash that Tr**p, e.g., keeps a copy of ******'s speeches by his bedside?
- Given Tr**p's White Supremacist attitude and Guam's Non-White majority (and don't think that Tr**p doesn't know about that), Tr**p's at the very least not going to care if the mostly-Chamorro Guamanian population gets hit by North Korea. Also, Guam is a United States territory as opposed to a United States state.
There are other reasons as well. Nonetheless, the four aforementioned reasons are sufficient-enough-to-mention reasons. By the way and as I have to reiterate, don't think that Tr**p doesn't know about Guam's demographics—anyone can look up Guam's demographic information in the "CIA World Factbook", and a racist and so-called "POTUS" like Tr**p would know about that as "POTUS". In other words, don't be fooled by someone as bigoted, narcissistic, and sociopathic (e.g., maliciously-shrewd and -calculative) as Tr**p wherein Guam is concerned or in any other case.
