WARSAW — With just days remaining until Donald Trump visits Poland, the political situation here continues to deteriorate, as it has been doing since November 2015.

That was when Poland began abandoning the path of democracy and the rule of law under the newly elected national-conservative Law and Justice party, led by its chairman, Jaroslaw Kaczynski. Its first victim was Poland’s Constitutional Tribunal, which emerged from a long legal battle a year later with its membership reconstituted, leaving it subservient to the government. Likewise, public radio and television, once far more independent, now broadcast pure propaganda that praises the government while demonizing Poland’s political opposition parties and the European Union as a whole.

A month ago, Poland’s president, Andrzej Duda, ignored a verdict of the Supreme Court. Then the government gave itself the power to rescind almost every decision of municipal mayors. On June 10, the police detained Wladyslaw Frasyniuk, a legendary leader of the Solidarity movement that resisted Soviet domination in the 1980s and a true hero of the Polish democratic opposition. He had been forcibly removed from a demonstration against Poland’s effective ruler, the party chairman Mr. Kaczynski. And on June 25 another demonstration against the government was attacked by right-wing extremists. A spokeswoman for Law and Justice was later quoted as saying she could understand the assailants.

Of the many warning signs we’ve seen in Poland, this was particularly ominous. But is it something that disturbs the current White House? In the past, it certainly would have done so. This time we do not know.
