Why stop at one? Given the incredible practicality of and undeniable security provided by massive Ming Dynasty-style fortifications, we the citizens of the United States of America beseech the ascending God Emperor to expand his glorious vision to include a wall which will completely surround the State of Texas. Citizens residing outside the state will be glad to be shielded from the boisterous and boastful Texans while proud Lone Star residents will enjoy a measure of peace of mind as the rest of the country inevitably descends into chaos and anarchy as swamp levels continue rise and the Constitution is amended 140 characters at a time.
Bonus points if the former host of The Apprentice can get Oklahoma to pay for the wall.
