for the first two words im not quiete sure what I should put at the moment maybe. some of the policies that harms mexico would be the U.S mexico border because with the border being there it causes a lot of problems because of the constant border patrol presance. another harm is the problem with illegal drugs next to the border.
plan: how to fix the first one is to spread the border partol out so their not all in one spot. and 2 increase the number of screenings.
the good things that will come out of this will be that less illegal immigrantes will be in the US and also less drugs will be in aswell.
