If the country is invading you, doesn’t that make them de-facto worse?

Conscription is a necessary tool for a defense effort. There are countries (Sweden, Norway) where conscription serves more as a mandatory civil service period. Those programs give citizens a much greater understanding of their government and society.

I would still fight injustice but make it clear through my expression of doing so that I don't support the current regime anymore than I otherwise would. Countries should consider themselves gratefully lucky the world accepts their existence and I'm not joining a collective just to be in a one-way relationship.
