Analysis of a scholarly article-Critical thinking

Argument:

There should be a debate since both parts have valuable arguments: Canada claims that the Northwest Passage is internal historical waters whereas the United States want to demonstrate that it is an international strait.

1. What is the stated premise?
As the Northwest Passage becomes more free of ice, the United States' argument that it is an international strait could gain popularity among other states because it would mean a shorter commerce route.

2. What is the hidden premise?
Therefore, Canada will have to reinforce its laws in order to keep its sovereignty over the Northwest Passage.

3. Is the statement completely accurate?
No, Canada is very creative in defending its interests. Moreover Canada and the United States have used many compromises throughout their history and maybe the Northwest Passage is more a periodical impass than an issue that needs a heated debate.

4. Do the premises inescapably lead to the conclusion?
No, we are not even sure that the ice is going to melt as fast as some may scholars may say and also going trough the Northwest Passage requires a special navigation equipment, which could discourage many navigators to use the Passage instead of the Panama Canal.
