It isn’t a matter of ghoulishness, read about the pilot in my post.
You have to be realistic and know that when our enemies lose an asset or a capability it lessens their ability to kill us, or those allied with us.
Red China or North Korea losing a trained submarine crew and officers is good news, losing important aircraft and pilots, ships and trained crews, all is good, ugly but good, it is better they destroy themselves than require American or Taiwanese, or South Korean, or Japanese, or Australian lives to kill them.
Those Chinese that died were not an immediate threat to us.
I am glad I don’t have your view of the world...”kill or be killed”.
You need to find Christ. Your heart is black.
God made those Chinese men just like He made you.
