If you look beyond Donald Trump's comprehensive unpleasantness — is there a disagreeable human trait he does not have? — you might see this: He is a fundamentally sad figure. His compulsive boasting is evidence of insecurity. His unassuageable neediness suggests an aching hunger for others' approval to ratify his self-admiration. His incessant announcements of his self-esteem indicate that he is not self-persuaded. Now, panting with a puppy's insatiable eagerness to be petted, Trump has reveled in the approval of Russian President Vladimir Putin, murderer and war criminal.

Putin slyly stirred America's politics by saying Trump is "very ... talented," adding that he welcomed Trump's promise of "closer, deeper relations," whatever that might mean, with Russia. Trump announced himself flattered to be "so nicely complimented" by a "highly respected" man: "When people call you brilliant, it's always good."

When MSNBC's Joe Scarborough said Putin "kills journalists, political opponents and invades countries," Trump replied that "at least he's a leader." Besides, Trump breezily asserted, "I think our country does plenty of killing also." Two days later, Trump, who rarely feigns judiciousness, said: "It has not been proven that he's killed reporters."
