President Joe Biden stunned pundits and politicians on Saturday when, at the end of a fiery speech in Warsaw, he seemed to endorse regime change in Russia, saying Vladimir Putin “cannot remain in power.” His speech caused a huge reaction, particularly among members of the media and public figures in areas of foreign policy and politics. That included a lot of people on social media comparing his commentary to Ronald Reagan’s historic “Tear Down This Wall” speech in Berlin in June of 1987.
