Is it better to be drafted now, or wait until Putin has another territory to "liberate"

Are you absolutely seriously asking whether it is better to almost cetrainly die now, or have a chance of dying in some hypothetical situation later? I'll choose the latter every single time, thank you..

Is it suddenly ok when it's Russia drafting "free" Ukrainians from those "liberated" territories?

No, it's also not OK. It doesn't happen on even remotely similar scale to what Zelensky is doing.

Are the kidnapped children free now? Happy? Doubtful.

Probably not.
At least they are alive in contrast to all the men Zelensky's regime kidnapped and sent to die.

Living there, it seems like you live your normal life. But you can’t express your thoughts, there are topics you can’t discuss, you can’t go where you want. You live like a spider in a jar. You are kept inside, and you run in circles like horses in a circus ring. Those who expect Ukraine to save us are having a hard time. It’s hard on morale. You’re not allowed to speak about Ukraine; Ukrainian symbols are banned. If you hear something, or say something they think is wrong, they grab you and put you in a basement.

So, the same as in Ukraine, but without the kidnappings and with an ability to leave at any time.
