" Regrettably, the Trump administration missed an opportunity to confront the Polish government about this new law. When President Trump visited Warsaw in July 2017, the law was under discussion but had not yet been enacted into law. He gave a vigorously nationalistic speech at Warsaw’s war memorial, calling for protection of borders and urging Poles to join Americans in fighting forces, “whether they come from inside or out,” that threaten the shared “values…of culture, faith and tradition.”11 Many in Poland saw this as a clear expression of support for PiS’s nationalistic tendencies. The Polish government was delighted with Trump’s speech, and he neither publicly nor privately said anything about the then pending legislation. "
