You sure do have a lot here for an Article that is only 143 words long. Where exactly is this process (with all the added explanation) you cite contained in Article V?
Seems to me a lot of it is supposition, views of prior concerned people and a mix. We’d have had a much better handle on “the process” had we (the US) done a Convention of States before.
The Framers’ process was intended to make the natural right of the people to suggest changes fairly easy to achieve.
However, changes should not be made lightly. That is why three-fourths concurrence is a wise and high bar.
Article V is written in 18th Century legalese. My explanation is written in modern English. No suppositions, just explication.
