Depends on the situation. I would accept conscription for myself as a measure of last resort ie. defence. I probably wouldn't be much use to them anyway so they would have to be really desperate!! I also kind of like how the Swiss military service works, everyone does it, knowing it will probably never be needed... because it teaches life skills etc.
On the other hand I don't think I could get behind the US conscription for Vietnam or Russia conscription for Ukraine.
