If someone invaded your country would you fight back?

Its funny, this topic, only because I was discussing with a  friend the other day, that they should have a voluntary combat training for citizens - like boot camp/basic training for citizens that want to be trained to be defenders. Like for those who choose not to serve in the armed forces, but want the training. I think that a combat-ready society is a good idea.

Isn't this what the Swiss government does?  Every male gets issued a firearm and has training with it.  I don't know if it's mandatory service in the Military though.  Somebody correct me if I'm wrong.
