Anti-Democracy advocate, Mixed government is the only good government
THE second point to be examined is, whether the [constitutional ]convention were authorized to frame and propose this mixed Constitution.
Think of it this way. If Texas was the largest producers of Widgets in North America Continent...but one tiny part necessary for the Widgets to function came from a source within the US...guess what could/would happen?
as to whether or not they can....well, you are forgetting about the very nature of being a sovereign currency issuer that comes with nationhood....I can speculate that infrastructure could be maintained superior to how it is now and be just as correct as you are.
if Texas becomes a nation, it is assumed it was an amicable split.... if it wasn't amicable, the US would invade and capture Texas and the secession wouldn't be successful in the first place.
