So, critics of the media on the right have become fond in recent days of defending Donald J. Trump’s congratulatory phone call to Vladimir Putin. They’re using an interesting — if nonsensical — argument.

Trump called Putin the other day against the advice of his national security team. He congratulated the Russian strongman on his re-election in what many have called a “sham election.” His soon-to-be-former national security adviser H.R. McMaster said that Trump shouldn’t congratulate Putin because of corollary issues that have clouded U.S.-Russia relations.

The president’s phone call has gotten plenty of criticism. I’ve joined the chorus of critics on this blog.

The push back was immediate. Trump defenders point out that Barack H. Obama congratulated Putin on his re-election in 2012.

Whoa! Hold on here! Let’s examine briefly the situation and how it compares with the here and now.

Vladimir Putin was a bad guy in 2012. I get that. He is worse now. Why? Oh, let’s see. He has meddled in our 2016 presidential election and is likely going to meddle in our midterm election this year, let alone in other countries’ elections; he used nerve gas on a former Soviet spy and his daughter.

President Obama did not have issues such as those on the table when he chatted with Putin in 2012. Donald Trump had a lot of them to toss at Putin when he called him just the other day.

There’s the difference.
