Thomas Sowell‘s last column of the year at Human Events puts 2015 under a miroscope.

It is always hard to know when a turning point has been reached, and usually it is long afterwards before we recognize it. However, if 2015 has been a turning point, it may well have marked a turn in a downward direction for America and for Western civilization.

This was the year when we essentially let the world know that we were giving up any effort to try to stop Iran — the world’s leading sponsor of international terrorism — from getting a nuclear bomb. Surely it does not take much imagination to foresee what lies at the end of that road.

It will not matter if we have more nuclear bombs than they have, if they are willing to die and we are not. That can determine who surrenders. And ISIS and other terrorists have given us grisly demonstrations of what surrender would mean.

Putting aside, for the moment, the fateful question whether 2015 is a turning point, what do we see when we look back instead of looking forward? What characterizes the year that is now ending?

More than anything else, 2015 has been the year of the big lie. There have been lies in other years, and some of them pretty big, but even so 2015 has set new highs — or new lows.

This is the year when we learned, from Hillary Clinton’s own e-mails, after three long years of stalling, stone-walling and evasions, that Secretary of State Clinton lied, and so did President Barack Obama and others under him, when they all told us in 2012 that the terrorist attack in Benghazi that killed the American ambassador and three other Americans was not a terrorist attack, but a protest demonstration that got out of hand. …

… Lies are a wall between us and reality — and being walled off from reality is the biggest deal of all. Reality does not disappear because we don’t see it. It just hits us like a ton of bricks when we least expect it.

The biggest lie of 2014 — “Hands up, don’t shoot” — had its repercussions in 2015, with the open advocacy of the killing of policemen, in marches across the country. But the ambush killings of policemen that followed aroused no such outrage in the media as any police use of force against thugs.
