If I entered your fenced property to save my life because someone is chasing me with a gun, It will not and should not be considered a crime. It would make more scene if the US leads the world to make investments to open factories in South America and hire those immigrants on their own countries. if half the money spent on wars by all countries are spent to make jobs, we would have more peace and justice. Finally I don't think any issue will be dealt with differently if different president is in office. It is the deep state that controls every thing while people are busy blaming the other side.
