Phase 4 is about "spillover:" the fact that conflicts often implicate more than just the affected country. As you continue to read up on your conflict, keep track of what other nations are involved, and in your updates, focus on the following questions: How does the conflict affect other countries? What outcome do the countries hope to see? How are they attempting to realize those outcomes?
You are no longer bound to the two news sources you used in Phase 3; in fact you may find that you'll find more direct answers to your questions in more specialized sources.
As usual, keep these posts short (no more than 200 words), and link any relevant articles or commentaries.
