A lot of you made the arguments that we should never because of the hatred you hold for Arabs. All tho I share the same sentiment regarding those people it is important to remember that when it comes to politics you should never frame your work around petty feelings. America, the most powerful country in the world is in Nato and in the Security Council of the UN. Even tho they may dislike the rest of the member they still remain steadfast on their path and goal, to be the most powerful entity. When you join such pacts, allies and or organisation you can work from within to reach your goal. The saying " keep your friends close and keep your enemies closer" came to mind. Why isolate ourselves from a globalising world. It would benefit us to be in a pact with other Muslim countries at least from a knowledgable point of view. We can form it the same way as the UN and have veto rights and have a say in their affairs.
Some might even argue that it is a bad idea to join because we could easily be subjugated by the other richer and more powerful states. Such a union could, with the right leader at hand, grant us, if we play our cards right, valuable role in the game of politics. We already have the resources we need (natural wealth such as oil and minerals etc.) If utilised correctly we can gain political allies, access to a whole new market and much more.
There are more sides to Islam than just Sunnism, Shias are not gonna be super hyped to join such pact, so the chances of it happening are slim to none btw.
