“Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tossed, to me:
I lift my lamp beside the golden door,
And I will build a great wall – and nobody builds walls better than me, believe me – and I’ll build them very inexpensively. I will build a great, great wall on our southern border, and I will make Mexico pay for that wall. Mark my words.” 

- 'Murica

I've just finished study of two years of U.S crime, immigration and the KKK, this is not the time to start the history war with a history student my friend, lay down your food and your weapons, this will not end well. 

Just joking, but you might be surprised by some of the realities of U.S 'unity', or not, depending on how cynical you are.
