A striking opinion piece in the NY Times by a former honcho at the CIA. When he was a government official he kept his presidential preferences to himself; he’s voted for both Democrats and Republicans; he’s not a member of either party. Now, he wants to explain why Hillary Clinton is a better choice than Donald Trump. Better. Not just preferable, but better.

Two strongly held beliefs have brought me to this decision. First, Mrs. Clinton is highly qualified to be commander in chief. I trust she will deliver on the most important duty of a president — keeping our nation safe. Second, Donald J. Trump is not only unqualified for the job, but he may well pose a threat to our national security.

I spent four years working with Mrs. Clinton when she was secretary of state, most often in the White House Situation Room. In these critically important meetings, I found her to be prepared, detail-oriented, thoughtful, inquisitive and willing to change her mind if presented with a compelling argument.

Two questions. Could anyone possibly claim that final sentence could be uttered to describe Trump? When he’s neither prepared nor detail-oriented nor thoughtful nor inquisitive nor willing to change his mind? And could anyone deny those are all vital qualities for the job Trump is applying for?

In sharp contrast to Mrs. Clinton, Mr. Trump has no experience on national security. Even more important, the character traits he has exhibited during the primary season suggest he would be a poor, even dangerous, commander in chief.

These traits include his obvious need for self-aggrandizement, his overreaction to perceived slights, his tendency to make decisions based on intuition, his refusal to change his views based on new information, his routine carelessness with the facts, his unwillingness to listen to others and his lack of respect for the rule of law.

But then, to balance that a little, there are his good qualities…Except that there aren’t. He has none. His bad ones crowd them all out – there’s no room left.

The dangers that flow from Mr. Trump’s character are not just risks that would emerge if he became president. It is already damaging our national security.

President Vladimir V. Putin of Russia was a career intelligence officer, trained to identify vulnerabilities in an individual and to exploit them. That is exactly what he did early in the primaries. Mr. Putin played upon Mr. Trump’s vulnerabilities by complimenting him. He responded just as Mr. Putin had calculated.

Mr. Putin is a great leader, Mr. Trump says, ignoring that he has killed and jailed journalists and political opponents, has invaded two of his neighbors and is driving his economy to ruin. Mr. Trump has also taken policy positions consistent with Russian, not American, interests — endorsing Russian espionage against the United States, supporting Russia’s annexation of Crimea and giving a green light to a possible Russian invasion of the Baltic States.

In the intelligence business, we would say that Mr. Putin had recruited Mr. Trump as an unwitting agent of the Russian Federation.

There’s more, but that’s a slam dunk right there.
