Ron Paul said same thing… however, the wall won't be what keeps us in. It will be but a relic when the technology comes that attempts to control us again. The statement is more of a warning against tyranny, because the tyrants will use everything in their favor. Keep in mind though, they use the lack of a wall in their favor as well.
For now, the wall symbolizes our resolve against mass unchecked illegals coming into our country. As long as we Patriots stand behind it. As long as Trump's fantastical Train maga's forward. We Win.
WE WIN BIGLY.
LETS BUILD THIS BEAUTY!
