Do we have the ability? Yes
Do we have the cajones? Remains to be seen
If we wanted to, we could be the environment difficult enough so that they would self deport and not come. How?
1. Aggressively and through all means necessary defend our borders.
2. Enforce all of our immigration laws and regulations to the fullest extent.
3. Punish/fine/jail all unscrupulous US employers who give illegals jobs.
4. Got off all infrastructure support--healthcare, education, welfare, etc.
5. Repeal the 14th amendment of the constitution that gives citizenship to the US born babies of illegal alien criminals.
If we did that....they'd self deport in a skinny Tijuana minute. And the very few who didn't we should........Find, Arrest and DEPORT, Deport deport.
