Input: That's Sen. John McCain's warning to the country -- and  his  party -- about the dangers of submitting to the rising tide of populism  isolationism and nationalism being sold by President Donald Trump.
The Arizona Republican's speech -- delivered at his alma mater US Naval Academy on Monday -- was the second time this month he has delivered a broad-spectrum critique of Trump and Trumpism. And the two speeches taken together are rightly understood as  McCain 's attempt -- while facing down a diagnosis of terminal brain cancer -- to serve as a clarion call for a GOP he believes has wrongly and dangerously fallen under the Trump trance. (Worth noting:  McCain  never uses Trump's name in this speech. But  the 45th President  is like a black cloud looming over the proceedings. )
Down that path lies real peril for the party and the country   McCain  believes  and  he  appears to be committed to doing everything in  his  power in the time  he  has left to sound the alarm.
(Although  side note: There is roughly zero chance this speech is not directed at Trumpism  but if  McCain  really wants people to wake up  why doesn't  he  plainly say that?)
Notice the sleeping metaphor  McCain  used in this passage from Tuesday's speech:
That's a series of powerful images from  McCain  -- a public ignorant of the necessity of its leadership  siloed off in echo chambers of our own making  defaulting to partisan politics and unwilling to engage with one another in search of compromise.
 McCain  casts this slumber as a fundamental break from the post-World War II order (and a remarkable blindness to what our post-World War II approach to the world wrought). This line gets at that this-is-not-normal message from  McCain :
The attack on our values -- which  McCain  makes clear is coming from within and without the United States -- requires an active decision to fight for what we believe in. That's the only way we can hope to keep what had made us great  according to  McCain .
At another moment in the speech   McCain  insisted that American values "are under attack from forces within liberal democracies themselves  parties that preach resentful nationalism rather than enlightened self-interest  nativism rather than equal justice."
The stakes  in  McCain 's mind  could not be higher. And the US populace could not be less prepared for what is increasingly a full-frontal assault on the values that make America  well  America.
 McCain  is trying to wake people up.  He 's like the town crier  going around banging a pot and insisting that if we don't recognize the threat posed by the Trumpism here and its ilk around the world  it may be too late.
