That country probably gave you the opportunity you have now. You might not think its worth 2 years, but the country does and everyone else in that country also did.
You should really think about going back and serving a country which gave you opportunities.
They really don't, most of my generation and their parents do everything they can to avoid it, but that aside:
I am all fine with serving my country, I would love to go back for e.g. 2 month per year or biannual to teach what I have gained to the next generation at a high school or university whatever even village schools.
The problem is military is not the one I could be the most useful, apart from the ethical questions. And they don't give you a choice about how you serve your country.
No. Fuck conscription. It's just a modern form of time-limited slavery, with indoctrination and abuse on top. It has no place in the modern world. I totally support people who flee a country to escape it.
