The wording in Mattis' letter reminded me of this DJT tweet from last December.

Remember Pearl Harbor lyrics https://www.lyricsmania.com/lets_remember_pearl_harbor_lyrics_sammy_kaye.html

"Let's REMEMBER PEARL HARBOR

As we go to meet the foe.

Let's REMEMBER PEARL HARBOR

As we did the Alamo.

We will always remember how they died for Liberty.

Let's REMEMBER PEARL HARBOR

And go on to victory."
