Disagreement, especially when providing factual information to discredit false memes designed to further the kind of ideology that allows enemies to grow stronger, which in turn leads to eventual, prolonged conflict, isn’t illustrative of a meltdown, it’s nothing more than the presentation of factual information.
The broader point is this: Had we stopped Communism in China, there might’ve been no conflict in Korea and Vietnam.  Had we dealt with Iran properly in the late ‘70’s there would not have been future conflict with them or Iraq.  Had we dealt with the Soviet Union properly, there wouldn’t have been a Mujahadeen, Al Qaeda, or Isis.  Had we dealt with Iraq properly the first time, there would’ve been no need for a second time.  The world could have been a far more peaceful and prosperous one today had it not been for all of the misguided Neville Chamberlains.  Head in the sand diplomacy has never worked, not once.  It has only made prolonged armed conflict an inevitability.
