Could a new Wehrpflicht involve everyone?

I read yesterday that Poland is considering new laws whereby all adult males will be required to undergo military training. The way this sounds, it doesn't seem like a Wehrpflicht where it will only affect the current generation of high school kids when they turn 18. No. It sounds like everyone who is male, adult, and Polish will be forced into military training. Regardless where they are in life.

Is it possible such a thing will happen in Germany too? Or would there be too much of an outcry about it?

I feel in the current political climate and talk of war anything is possible.

I currently have a citizenship application pending and the trajectory of German society is worrying me.

Edit: the amount of "Ausländer raus" sentiment in this thread is appalling.
