On June 12, 1987, United States(US) President Ronald Reagan stood at the Brandenburg Gate, at the Berlin Wall that had divided East and West Germany since 1961, and he famously implored then Soviet Union leader, Mikhail Gorbachev to "tear down this wall".
Two years later on November 9, 1989, the wall came down when East and West Germany were reunited as the Cold War fizzled. Back then, it was the vision of the leaders to remove walls, barriers and iron curtains from hindering the peaceful exchange of common civility, relations and interactions among people as well as to promote democracy and liberty.
That was Ronald Reagan's vision. Since then, Europe has merged into a single economic market with common political themes under the European Union(EU), which permits safe visa-free no-borders interaction between States.
Donald Trump is no Ronald Reagan. Thus, in 2017, the new administration in the White House has committed to partitioning the Americas with the building of a wall along the US southern border with Mexico. The decision by the administration to build the wall fulfills a campaign promise by Donald Trump to do such to curtain Mexican immigration to the US.
Moreover, the new administration in Washington also plans to deport thousands of illegal immigrants living in the US and to restrict and to curtain immigration from many Muslim nations.
The character of the US Republic that was built, made strong and sustained by immigrants, is making an unprecedented change. The scope and the future of the Republic can no longer be accurately determined at this time. Yet, among other things, one thing is for sure so far: the new administration in the White House is guilty of partitioning the Americas.
