Trump's tweets are a goldmine for spies, and they can use them to anticipate his next move or even determine what they will be.

Mexico was just ranked the second deadliest country in the world, after only Syria. Drug trade is largely the cause. We will BUILD THE WALL!

Trump’s Twitter feed is a gold mine for every foreign intelligence agency. Usually, intelligence officers’ efforts to collect information on world leaders are methodical, painstaking and often covert. CIA operatives have risked their lives to learn about foreign leaders so the United States could devise strategies to counter our adversaries. With Trump, though, secret operations are not necessary to understand what’s on his mind: The president’s unfiltered thoughts are available night and day, broadcast to his 32.7 million Twitter followers immediately and without much obvious mediation by diplomats, strategists or handlers. 

Intelligence agencies try to answer these main questions when looking at a rival head of state: Who is he as a person? What type of leader is he? How does that compare to what he strives to be or presents himself as? What can we expect from him? And how can we use this insight to our advantage? 

At the CIA, I tracked and analyzed terrorists and other U.S. enemies, including North Korea. But we never had such a rich source of raw intelligence about a world leader, and we certainly never had the opportunity that our adversaries (and our allies) have now — to get a real-time glimpse of a major world leader’s preoccupations, personality quirks and habits of mind. If we had, it would have given us significant advantages in our dealings with them. 

Trump’s tweets offer plenty of material for analysis. His frequent strong statements in reaction to news coverage or events make it appear as if he lacks impulse control. In building a profile of Trump, an analyst would offer suggestions on how foreign nations could instigate stress or deescalate situations, depending on what type of influence they may want to have over the president.

Great, so not only is Trump embarrassing the country with his constant tweeting, but he is also allowing foreign spies to monitor and perhaps manipulate him like no other president before him.

A little further down in the article are these two paragraphs: 

What Trump doesn’t say can be very revealing, too. For instance, the lapse of time between when the USS Fitzgerald collided with a cargo ship off the coast of Japan (12:30 p.m. on June 16, in Washington) and when the president tweeted about the incident (10:08 a.m. the next day) was nearly 23 hours. The tragedy marked the U.S. Navy’s most significant loss of life aboard a vessel since terrorists bombed the USS Cole in Yemen in 2000. 

Typically, a president would quickly make public remarks about a significant military loss. With Trump, intelligence analysts would note the inconsistency compared with previous administrations and search for similar patterns. Is Trump so hands-off that he waited for his secretary of defense to speak? Did something else capture his attention during those hours that he found to be a higher priority? Between the crash and his first public statement about it, Trump tweeted a video of his remarks on a new Cuba policy, a picture of himself signing the Cuba memorandum and a reference to his campaign promise about Cuba; he also retweeted Sean Hannity, a Fox News personality, promoting an upcoming show on the “Deep State’s allies in the media” working to undermine Trump. 

Fairly easy to determine from his tweets that Trump does not know how to respond to a national crisis or emergency until he receives instruction from his aides, but has a knee jerk reaction to every perceived slight which inspires a quick and most often inappropriate off the cuff response.

At the end of the article there is this observation:

Even deleted tweets would be of interest. Trump mostly appears to delete tweets because of spelling errors, later replacing them with a correction. For an intelligence analyst, this would confirm that Trump’s Twitter feed really is a raw insight into his thought process, without much input from aides. 

Analysts would also be likely to use technology to perform content analysis on the president’s tweets in the aggregate. Intelligence agencies can employ a more robust version than the open-source projects that news organizations have used, because they can marry Trump’s tweets with information they collect through intercepts and other means. Software could look for patterns in speech or word categories representing confidence related to policy, whether Trump is considering opposing points of view and if he harbors uncertainty toward any subject. Computers can perform metadata analysis to build timelines and compare Trump’s Twitter feed with his known public schedule, creating a database of when and where he tweets and what else he’s doing at the time. Anything that provides a digital footprint adds context to the analysis. 

Trump says it’s the press’s fault that he uses Twitter as much as he does. His aides clearly want him to stop, but the president just as clearly wants and needs to be heard unfiltered. Fortunately for him, the platform lets him speak directly to his supporters whenever he chooses. Unfortunately for the rest of us, they aren’t the only ones listening.

So there you have it, yet another reason to be mortified, and possibly even terrified, by this presidency.

You know when I pictured a Trump presidency I quite literally pictured an apocalyptic landscape where the entire country was in various stages of decay and self destruction.

I actually think I might have underestimated how bad it was going to be.

We're not even half way through the first year yet.
