A false dichotomy

divides people between isolationists and interventionists.

Far too crude a distinction.

The real issue is: WHICH foreign conflicts should the U.S. engage in?

Definitely not over who controls Ukraine.

1. The historical record, concerning the legitimacy of the respective claims, is mixed.

2. In any case, what difference does that make to the U.S.?

Next to nothing.

OTOH, consider something that really matters to the U.S.:

Who controls Germany.

Now Germany is an independent, self-governing country.

But suppose it were a province of the Russian Federation.

That would really be significant to the U.S.

The point is:

All foreign interventions are not equally significant (to or for America), or justifiable.
