I get that Donald J. Trump wants to open up lines of communication between his office and those of other world leaders.

The president’s motives appear to be noble.

But hold on! He’s giving out his personal, private cellphone number to those other leaders? Is that what I’m hearing?

Whoa, Mr. President!

Cellphones aren’t secure. I keep hearing how they’re vulnerable to, um, hacking. People can listen in. Bad people can listen and do terrible things in reaction to what they hear.

And so the president of the United States wants to talk openly, and I presume candidly, with world leaders about the myriad problems facing the world.

If the president wants to maintain open communications with other leaders, I have an idea. Let ’em call you on the secure line in the Oval Office, or in the Situation Room.

Handing out personal cellphone numbers is fraught, shall we say, with some serious national security concerns. Don’t you think?

And didn’t the president — when he was running for the office — bellow incessantly about all the alleged security breaches created by Hillary Clinton’s use of her personal e-mail server while she was secretary of state?

I am shaking my head.
