my nation does not provide me something worth defending at the cost of my life.

I get that young people are angry at german politics (and rightfully so). But at least we get to live in a mostly democratic, free country, where you can express that anger and not governed by a power hungry dictator that will have you prisoned and/or killed for criticising them. That alone seems worth defending for me.

Looking at history, after they unsuccessfully tried to invade Russia in winter, while at the same time trying to take over Europe.
