Put up a 50’ high wall across it’s northern and small western border and let them have at it. They can have a trade agreement with the country of California. I’m sure both countries will thrive.
Uhhh hell no. Feel free to give them Massachusetts though - hell, give ‘em New England and declare it a separate country. Then build another wall.
