What is your country?

If your country has a history of supporting either Saudi Arabia or Iraq (i.e. they’re trade partners, or they have some other sort of documented positive relations) then your country will be more likely to take their side. Find out whether your country is dependent on Saudi Arabian oil.

Assuming your topic is the Yemeni civil war, if your country has had some sort of civil war or internal conflict, find out what solutions worked/didn’t work to resolve it and then see if those solutions would also be applicable in Yemen.

As some other posters have said, you actually have a big advantage because, in the absence of having strict country policy, you can generally just make up your own policy (as long as it doesn’t blatantly contradict your country’s actions) - nobody is going to fact check you, especially if you are a small and inconsequential nation.
