Bush I was the architect of the Bush Plan for North Mexico (aka USA).
It was his responsibility to implement the enforcement and border security portions of that amnesty bill that we never saw.
The reason we have 30 million illegal aliens is the next 4 Presidents refused to enforce the laws and borders.
Actually, Republicans were complicit, too. And that is another issue.
It is the “Wimpy” version of political promises.... “I'll gladly pay you Tuesday for a hamburger today” only the hamburger is never paid for.
