It comes down to this - Denmark completely rely on the international community, particularly the EU and US for defense.

If that fails, and let's say hypothetically, Germans attacked, what can Denmark do? Surrender in 4 hours is the preferred play.

That denmark should not have a defence? I think thats wrong, even if it cant resist the enemies on its own. Its a lot easier to get your allies to help you while you are figthing to defend yourself instead of asking your allies to reconquer your contry.

I take your 4 hour surrender snark, but saying its preferred is properly too much for a one time occurence.
