The question in essence was asking for what events would increase the sales of oil. It's important to consider what is being said about the product.  "More people embrace the oil free diet" is a clear example of something that'd cause a loss in profits therefore belonging on the left side.

I mean... Eventually some kings left the Papal authority. However, remember the crusades? It united nearly everyone in Europe. Some to the point of making new states.

Hello! 
The answer to your question is "Palestine lack a single representative", even though this option is not exactly accurate. Palestina have diplomatic representatives since they have participated in the different agreement meetings with Israel, but Palestina is not recognized as an State by the United States and most of the European Union. This lack of support to the Palestinian representatives is one of the main impediments to reach an agreement betweent Israel and Palestine.
Hope this helps
