Nuclear missiles in Cuba?

[Anomalocaris]

If Cuba joins in a military Alliance with either and either country puts missiles there then America has no right to do anything other than convincing them not to.

What the US has the right to do and what the US can do are two very different kettles of fish (not very different from any other great power).

If a country only does what everyone would agree it has the right to do, then the chances are it won’t be able to exercise its right to exist, even if everyone agree it has that right, for very much longer.

Rule system can serve many causes, some noble, some not so noble.   There are many rewards associated with any well contrived rule system.   But there is one thing that all rule system will inevitably do, that is it will eventually bring the greatest reward to the one who breaks it in the most cunning and opportune manner.
