If we observe the actions of the United Soviet Socialist Republic, we may note that it is doubtful a peaceable and amenable divorce could be attained. Therefor, if any of the several states wee to attempt to break themselves from the union and that action were met with either unreasonable demands or military action, the union that is the United States of America would be acting in the same manner as its former foe, which has since failed as an entity. This would not be in the best interest of the inhabitants. This response would be both despotic and totalitarian in nature.
It is our right, as citizens of a free nation, to enter or to leave this Union as we see fit. I would therefor propose that the Western Alliance of States be formed, comprising the areas of Montana, Idaho, Washington, Utah, Wyoming, Colorado, Arizona, New Mexico, and Texas. Being the several states most similar in political and cultural values, it is most likely that these nine states would act in the best interests of their own citizens, devoid of the unreasonable levies and responsibilities forced upon us by citizenry of vastly differing viewpoints. These states could then peacefully negotiate with the remaining American States in order to maintain the defense and stability of the continent.
The effective end of a peaceful dissolution would not be a death blow to the American was of life. Rather the opposite. A peaceful dissolution of the Federal Government of the United States would mean a MORE active role in international relations. Just as their withdrawal from the Soviet Union has given the various eastern European nations their own voice in the world, so would ours now be heard. Rather than the single, increasingly unrepresentative voice our nation now offers to the world, we would now be able to approach international relations with perhaps as many as 50 individual views, as 50 individual nations. Perhaps we would be united in cause, but each with our own unique view, our own unique voice, to better represent the citizenry from which the law and culture arises.
*Edit- I felt compelled, after some discussion with my father-in-law, to amend this post to a degree. I would note that my Constitutional studies are limited in scope and are mostly freelance, but after reading the Constitution, I felt the need to strike a line and amend it. Article I Section 10 of the United States Constitution does, in fact, prohibit the states from entering into treaties. My intent was to show that states can, indeed, enter into agreements, such as the Western Student Exchange program, the Western States Hunting Alliance, and similar. As I have not properly researched the applicable laws, or their place as relates to the federal government, I have stricken this reference entirely.
