Coming from software development, it is very useful to have a bug tracker or issue tracker to focus discussions and to know which problems are still unresolved.
In the case of this forum, each issue would be a specific concern against leaving the US, as narrowed down as possible, and people would propose solutions or compromises to appease people with those concerns.
While a concern is unresolved, the issue would have an “Open” tag, and once a good solution has been found that most of the people can agree with (even those against leaving the US), then the tag would be changed to “Closed”.
Each issue would be identified by the topic number that appears in the URL, so in order to link to a related issue one just has to use the topic number (I believe this platform allows this).
The moderator would have more work to do: (1) he would have to close duplicate topics, or (2) reframe issues in case they are too wide. But the pay off is more organization and concentrated efforts.
Also, issues could be assigned to one user, who would be in charge of keeping up to date the pros and cons of the proposed solutions.
Can something like this be done in this forum, emulating Github or Gitlab?
