The following is an excerpt from historian Heather Cox Richardson’s blog. The rest of the post is about the January 6 Commission’s efforts to get to the bottom of Trump’s role in the insurrection.

On July 27, 2016, even before the Republican National Committee changed the party’s platform to weaken the U.S. stance in favor of Ukraine in its struggle to fight off Russia’s 2014 invasion, U.S. News & World Report senior politics writer David Catanese noted that senior security officials were deeply concerned about then-candidate Trump’s ties to Russia.

July 27 was the day Trump referred at a news conference to his opponent and then–secretary of state Hillary Clinton’s emails that were not turned over for public disclosure from her private server and said: “Russia, if you’re listening, I hope you’re able to find the 30,000 emails that are missing, I think you will probably be rewarded mightily by our press.” (We know now that Russian hackers did, in fact, begin to target her accounts on or around that day.)

Former secretary of defense Leon Panetta, who served under nine presidents, told Catanese that Trump was “a threat to national security,” not only because of his call for help from Russia, but because of his suggestion that he would abandon the North Atlantic Treaty Organization (NATO) if he were elected and, as Catanese put it, “his coziness toward Russian President Vladimir Putin.”

Former National Security Advisor Thomas E. Donilon also expressed concern over the hack of the Democratic National Committee by Russian operatives, and said that such an attack mirrored similar attacks in Estonia, Georgia, and, most prominently, Ukraine. He called on officials to confront Russian leaders publicly.

Cybersecurity expert Alan Silberberg told Catanese that Trump looked like an ally of Putin. “The Twitter trail, if you dig into it over the last year, the Russian media is mirroring him, putting out the same tweets at almost the same time,” Silberberg said.

“You get the sense that people think it’s a joke,” Panetta said. “The fact is what he has said has already represented a threat to our national security.”

Putin’s attempt to destroy democracy in Ukraine militarily has invited a reexamination of the cyberattacks, disinformation, division, attacks on opponents, and installation of puppet leaders he used to gain control of Ukraine before finally turning to bombs. This reexamination, in turn, has led journalists to note that those same techniques have poisoned politics in countries other than Ukraine.

Over the weekend, British investigative journalist Carol Cadwalladr warned that we are 8 years into “The first Great Information War,” a war sparked by Putin’s fury at the removal of his puppet Viktor Yanukovych in February 2014 from the presidency of Ukraine. Putin set out to warp reality to confuse both Ukrainians & the world. The “meddling” we saw in the 2016 election was not an attempt to elect Trump simply so he would end the sanctions former president Barack Obama had imposed on Russia in 2014 after it invaded Ukraine. It was an attempt to destabilize democracy. “And it’s absolutely crucial that we now understand that Putin’s attack on Ukraine & the West was a JOINT attack on both,” she wrote.

Today in The Guardian, political and cultural observer Rebecca Solnit wrote a piece titled “It’s time to confront the Trump-Putin network.”
