Unfortunately, your post runs afoul of the /r/AskHistorians rules on poll-type questions located in the sidebar:

No "poll"-type questions

"Poll"-type questions aren't appropriate here: "Who was the most influential person in history?" or "Who was the worst general in your period?" or "Who are your Top 10 favourite people in history?" If your question includes the words "most" or "least", or "best" or "worst" (or can be reworded to include these words), it's probably a "poll"-type question. These questions do not lend themselves to answers with a firm foundation in sources and research, and the resulting threads usually turn into monsters with enormous speculation and little focussed discussion - and, as such, are banned here.

This is explained in more detail in this [META] thread.

You could reword your question to ask something like "what significant developments occurred in the Middle East after World War I and why were they significant" to be more in line with rules as they stand.

This submission has been removed because it violates the rule on poll-type questions. These poll-type questions do not lend themselves to answers with a firm foundation in sources and research, and the resulting threads usually turn into monsters with enormous speculation and little focussed discussion. “Most”, “least”, "best" and "worst" questions usually lead to vague, subjective, and speculative answers.

For questions of these types, we ask that you redirect them to more appropriate subreddits, such as /r/history or /r/askhistory.
