Suggested text to write on your postcard to the South Korean embassies:
'Conscientious objection to military service is a human right. Contrary to international obligations, currently over 250 young people are imprisoned for refusing military service in the Republic of Korea.
I am writing to urge your government to immediately release them, and stop imprisoning those who refuse military service in the future.
Please feel free to adapt this. If you can, you can also include your own address and ask for a reply.
