That was just one of many deranged tweets from “the president” today. He’s more bonkers than ever, he’s more self-obsessed than ever, he’s as recklessly indifferent to the fate of the country and the world as ever. He’s also very very cross.

President Trump, in a series of angry and defiant tweets on Sunday morning, sought to shift the blame to Democrats for Russia’s virtual war to meddle in the 2016 election, saying that President Barack Obama had not done enough to stop the interference and denying that he had ever suggested that Moscow might not have been involved.

Mr. Trump, who has said little to publicly acknowledge a threat to American democracy that even one of his top aides called “incontrovertible” on Saturday, asserted that the efforts to investigate and combat the Russian meddling had only given the Russians what they wanted, saying that “they are laughing their asses off in Moscow.”

They are, of course, but not for the reason Trump claims. They’ve been doing it ever since November 8, 2016.

The president has repeatedly seized on the fact that the efforts started before he became a candidate, but has glossed over the conclusion that they evolved toward supporting his candidacy.

By “glossed over” they mean “totally and mendaciously ignored.”

In another tweet on Sunday, Mr. Trump, who has tried since the campaign to sow doubts about who was behind the election intrusions, said that he had “never said Russia did not meddle in the election,” quoting a comment he made in a 2016 presidential debate.

“I said ‘it may be Russia, or China or another country or group, or it may be a 400 pound genius sitting in bed and playing with his computer,” Mr. Trump wrote. “The Russian ‘hoax’ was that the Trump campaign colluded with Russia — it never did!”

Yet he has repeatedly denied that Russia was behind any meddling, even going so far in November as to suggest that he believed President Vladimir V. Putin’s denials of interference over the conclusions of American intelligence agencies.

“Every time he sees me he says, ‘I didn’t do that,’ and I really believe that when he tells me that, he means it,” Mr. Trump said at the time, calling questions about Moscow’s meddling a politically motivated “hit job.”

He blew kisses to Putin at the dinner table, he went over and had a cozy intimate chat with him with only the Russian interpreter for a third.

Mr. Trump has long fought the idea that Moscow’s efforts might have influenced the election, viewing it as a threat to his legitimacy. He has made little if any public effort to rally the nation to confront the Russians for their intrusion.

Always hedging. He has made zero effort, and he has made strenuous effort to do the opposite.

On Saturday, the president’s national security adviser, Lt. Gen. H.R. McMaster, said, referring to the Russian meddling, “With the F.B.I. indictment, the evidence is now really incontrovertible and available in the public domain.”

In a late-night tweet on Saturday, Mr. Trump criticized General McMaster for not saying at the security conference in Germany where he was speaking that the election results had not been changed as a result of the Russian interference. The nation’s intelligence agencies believe that it is not possible to make such a conclusion.

Trump is apparently too stupid even to grasp why it is not possible to draw such a conclusion.
