In my novel, a fantasy army emerged from a portal and tried to invade our world, only to be defeated by Earth's powerful military. 2 days after reclaiming Sydney (ground zero of the invasion), the 5 permanent security council member states (China, Russia, US, France, Britain) announced that they will, in the name of UN, form an expeditionary force and invade the fantasy world in the name of revenge without consulting other nations. (full plot idea: http://www.writingforums.org/threads/nebie-needs-help.140764/) How will other countries react to this incident? How will NGOs (Non Government Organizations) react to the security council's decision? What about media and the public? What will your own reaction be? PS: I have got some ideas for certain countries (eg Australia will most likely join the expeditionary force in the name of vengeance , Israel may want the US to focus on the security issues in the Middle-East instead) but it is always good to listen to your constructive opinion (and criticism) so feel free to leave your thoughts below.
