I think he translates "the best we can" to mean,
"the best we can while staying on task for creating the North American Union, with one common border."

It seems that every time I hear a comment, from anyone in government, about what is being done about with illegal immigration and the corresponding murders, rapes, gang activity, drug trafficking, and other social problems associated with these criminals, the speaker has a hispanic surname. Perhaps if our government did not have the fox watching the hen house, then maybe the problems would be evaluated correctly and dealt with.
