Retired four-star Army General Stanley McChrystal, whom former President Barack Obama sacked in wartime in 2010 over insubordinate remarks he made in Rolling Stone, told host Martha Raddatz over the weekend that President Donald Trump is immoral and dishonest.

The interview with McChrystal aired Sunday on ABC’s “This Week.”

“I think it’s important for me to work for people who I think are basically honest, who tell the truth as best they know it … I don’t think [President Trump] tells the truth.”

“I’d say no,” McChrystal answered when asked if he would accept a hypothetical invitation to join the Trump administration.

“Is Trump immoral, in your view?” asked Raddatz.

“I think he is,” McChrystal answered.

Though the sacked general received considerable blowback from the public and the press following his sharp criticism of Obama and his administration back in 2010, many on the Left have welcomed McChrystal’s putdowns of the current commander-in-chief with open arms.

The former top commander who led America’s Joint Special Operations Command during the war in Afghanistan criticized Trump’s military decisions.

He also cautioned individuals who might consider replacing recently fired Secretary of Defense James Mattis to ensure that they can truly be loyal to Trump given his approach to governance, his values, and his worldview.

He encouraged Trump supporters to “stand in front of that mirror” and carefully consider whether they are really willing to “throw away or ignore some of the things that people do that are pretty unacceptable normally just because they accomplish certain other things we might like,” he said.

“If we want to be governed by someone we wouldn’t do a business deal with because their background is so shady, if we’re willing to do that, then that’s in conflict with who I think we are,” McChrystal said.

In other words, do Trump’s many accomplishments justify Americans’ tolerating the unconventional approach he takes at times to achieve them — do the ends justify the means?

McChrystal praised the decision by Mattis to resign — and noted that his public disagreement with Trump over military strategy may “cause the American people to take pause,” presumably to consider the possibility that Trump is leading America astray.

“If we have someone who is as selfless, as committed as Jim Mattis, [who] resigns his position … we ought to ask what kind of commander-in-chief he had that Jim Mattis, the good Marine, felt he had to walk away.”

“If you pull American influence out [of Syria], you’re likely to have greater instability, and of course it will be much more difficult for the United States to try to push events in any direction,” said McChrystal, responding to Raddatz’s question about what difference it would make if 2,000 U.S. forces left that country.

He added that the strategy of pulling troops out and allowing the region to run itself “has not done well for the last 50 or 60 years” and that he does not believe — contrary to President Trump’s assertions — that ISIS has been defeated.

“I don’t believe ISIS is defeated. I think ISIS is as much an idea as it is a number of ISIS fighters … as long as the fertile ground exists, the causes that cause people to flock to a movement as extreme as ISIS exist, you’re going to have it flare back up again,” he said, adding that there is some intelligence that suggests there are more ISIS fighters around the world now than there were a couple of years ago.

McChrystal disagreed with Trump’s plans to withdraw troops not only from Syria but from Afghanistan as well.

McChrystal also told Raddatz that the soldiers who came forward to have Trump sign their hats during his surprise Christmastime visit to Iraq and Germany had violated the “spirit” of a military rule that prohibits military personnel from showing any political leanings while in uniform.

“Just when we were starting to sit down with the Taliban, just when we were starting to begin negotiations, he [Trump] basically traded away the biggest leverage point we have,” McChrystal insisted, referring to Trump’s announcement that he intends to bring the troops home.

President Trump responded to the media’s breathless — and false — accusations that he himself had brought the hats to distribute to the troops with characteristic bluntness, chastising the “fake news universe” and saying, “If these brave young people ask me to sign their hat, I will sign.”

CNN & others within the Fake News Universe were going wild about my signing MAGA hats for our military in Iraq and Germany. If these brave young people ask me to sign their hat, I will sign. Can you imagine my saying NO? We brought or gave NO hats as the Fake News first reported! — Donald J. Trump (@realDonaldTrump) December 27, 2018

In a series of tweets on Monday morning, Trump commented on his intention to bring the troops home — as he promised while on the campaign trail.

He also had some choice words for “failed generals who were unable to do the job before I arrived, like to complain about me & my tactics, which are working.”

“If anybody but Donald Trump did what I did in Syria, which was an ISIS-loaded mess when I became president, they would be a national hero. ISIS is mostly gone, we’re slowly sending our troops back home to be with their families, while at the same time fighting ISIS remnants…”
