Here's an interesting and alarming point of view.
From Fox -
"As the Trump administration continues to rattle sabers at North Korea with rhetoric eerily similar to the run-up to the U.S. invasion of Iraq in 2003, the possibility of a preventive U.S. war with North Korea may be more real than foreign and defense policy experts recognize....
The three so-called “adults in the room” who are apparently the strongest voices influencing President Trump’s foreign policy are National Security Advisor H.R. McMaster, Secretary of Defense James Mattis and White House Chief of Staff John Kelly.
McMaster is an active duty lieutenant general in the Army. Mattis and Kelly are retired Marine Corps generals.
Their common experience is commanding ground forces in the Iraq War. If they are shaping the Trump administration’s North Korea policy, it stands to reason that their views would have a decidedly military tilt." (My highlights)
A 'preventive' war with North Korea would be total hell. Here's why | Fox News
Let's hope McMaster et al learned NOT to get involved in these kinds of wars. I would love to see no more wars in my lifetime.
