Rather odd to think that having 50 states feverishly printing money will lead to greater monetary stability than the federal reserve system we have now. We tried that approach under the Articles of Federation, and it didn’t work.
If you can’t get 3/4s to amend the constitution, you can’t get 3/4s for secession. Anything less would be rebellion, and would be punished harshly.
Oh, you won't get secession by going through channels. That's like asking your wife for permission to start an affair. You have to just do it and be willing to suffer the consequences. There will be no turning back or the punishment will be harsh but I think a persuasive case can be made both to Texans and to Washington to let it happen once the move is made.
For example, how does it look to the rest of the world if the U.S. tries a violent putdown of Texas while condemning Russia for a violent putdown of Georgia and Chechnya? We might actually get a lot of diplomatic support from all the America-haters that either Bush or Obama have ticked off.
