Many soldiers genuinely volunteer to join the army (aren't conscripted), especially in western democracies. For the most part the powerful volunteer armies of democracies deter authoritarian regimes from committing endless atrocities. The alternative is tyranny. The right for government to conscript is still recognized in many of the most democratic countries and general conscription still happens in quite a few.
We need volunteer armies and accordingly soldiers who honor the nation deserve respect. In the meantime we can dream pf a future without war or the constant threat of war.
