President Donald Trump gave a brief history lesson on Poland's recent invasions during a Warsaw speech Thursday. In a few brief lines, he discussed Adolf Hitler, the Holocaust, and the Soviet invasion of Poland. Ultimately, Trump deemed the attack was "tough."

Twitter reacted with both confusion and sarcasm. Some users noted that it didn't make sense for the president to be telling the Polish crowd their own history, while others wrote that it sounded like a speech written for an elementary school.

Others users found that his brief analysis was reductive and superficial, with some users calling his speech a "history for dummies."

Others users said that they felt ashamed at the way the president was representing America overseas.

"Then 19 years later, in 1938, you were invaded yet again; this time by Nazi Germany from the west and the Soviet Union from the east. That's trouble. That's tough," Trump said before commenting on the Holocaust.

"A vibrant Jewish population, the largest in Europe, was reduced to almost nothing after the Nazis systematically murdered millions of Poland's Jewish citizens, along with countless others during that brutal occupation," he said.

"In the summer of 1944, the Nazi and Soviet armies were preparing for a terrible and bloody battle right here in Warsaw. Amid that Hell on Earth, the citizens of Poland rose up to defend their homeland."

Trump's speech was rapturously received by the Warsaw crowd, although a report by Newsweek wrote that the ruling party in Poland guaranteed the response for Trump Thursday by bussing people to stock the crowd full of pro-Trump supporters.

"Supporters will be bussed to Warsaw, the scene of Trump’s speech Thursday, from all over Poland to participate in what has been deemed a 'great patriotic picnic,'" read the report.

This factor got quickly picked up on Twitter, and overshadowed much of the chatter about the speech.
