Just stop every truck crossing into the USA carrying produce from Mexican farmers and tell them they have to be searched top-to-bottom for terrorists trying to sneak into the country...now it might take a few weeks/months to search them, so just park them on the side there until we have time...and if the apples, oranges, mangoes, go bad well that’s life...but if Mexico would help us control the border, maybe we’ll have time to search them quicker.
Not sure if stopping imports would be a solution. It cuts both ways.
