First, the city would lose a significant portion of its population. The border states are home to over 10 million people, which is more than the population of Washington, DC itself. If these states were to leave the union, it is likely that many of these people would move away from the city.
Second, the city would lose a significant portion of its tax revenue. The border states contribute billions of dollars in tax revenue to the federal government each year. If these states were to leave the union, this revenue would be lost, and the city would have to make up for it in other ways.
Third, the city would lose a significant portion of its political power. The border states have a significant number of representatives in Congress, and they have a strong voice in national politics. If these states were to leave the union, the city would lose this voice, and it would be less likely to get its priorities heard in Washington.
Finally, the city would be more vulnerable to attack. The border states provide a buffer between Washington, DC and other states that may be hostile to the city. If these states were to leave the union, the city would be more exposed to attack from these states.
In conclusion, the border states play a vital role in the survival of Washington, DC. If these states were to leave the union, it would have a significant impact on the city and could make it a less viable place to live and work.
