Your items 1 & 2 alone would solve the problem:
“1) Secure our borders
2) Enforce existing law”
If no additional illegals come into the country, that would stop the flow, which is the real problem.
Wikipedia on the US/Mexico border:

There are an estimated half a million illegal entries into the United States each year.
Wikipedia on the Paladin:
So to cover the border we'd need 1,954 / 22 ≈ 89 Paladins… but that's an under-count because that would entail butting them directly on the border. We would actually want them back a bit.Crew: 6 Effective firing range: 11 mi Operational range: 216 mi
c² = b² + a² 11² = 5.5² + a² 121 = 30.25 + a² 90.75 = a² 9.5 ≈ aSo, we could put them 5.5 mi away from the border, allowing them to cover 19 mi of border; this would mean that we'd need 1,954 / 19 ≈ 103 paladins [103 * 6 = 618 men].
See, securing the border is not as hard as they make it out to be.
