Trump – of course – is in a snit. Mattis didn’t resign, Trump retroactively fired him after he said he was resigning! So there and ha!

I am pleased to announce that our very talented Deputy Secretary of Defense, Patrick Shanahan, will assume the title of Acting Secretary of Defense starting January 1, 2019. Patrick has a long list of accomplishments while serving as Deputy, & previously Boeing. He will be great!

The Times reports:

Aides said that the president was furious that Mr. Mattis’s resignation letter — in which he rebuked the president’s rejection of international allies and his failure to check authoritarian governments — had led to days of negative news coverage. Mr. Mattis resigned in large part over Mr. Trump’s hasty decision to withdraw American forces from Syria.

When Mr. Trump first announced that Mr. Mattis was leaving, effective Feb. 28, he praised the defense secretary on Twitter, saying he was retiring “with distinction.” One aide said that although Mr. Trump had already seen the resignation letter when he praised Mr. Mattis, the president did not understand just how forceful a rejection of his strategy Mr. Mattis had issued.

Hahaha no, it takes reading comprehension to figure that out. Mattis didn’t say “You, sir, are a fat-headed dope and a menace,” so Trump didn’t get that it was implicit in what Mattis did say.

The president has grown increasingly angry as the days have passed, the aide said. On Saturday, Mr. Trump posted a tweet that took a jab at Mr. Mattis, saying that “when President Obama ingloriously fired Jim Mattis, I gave him a second chance. Some thought I shouldn’t, I thought I should.”

So neener-neener. Or something.
