It's .. ridiculous for Diamond to demand that the West make reparations from slavery, in light of the fact that Muslims were the major culprits when it came to slavery.
LOL. I do love Western revisionist history. We are innocent because everyone else is more guilty, regardless of the truth behind that.
As far as the reparations I demand, for African countries, naturally the US, Britain, and Spain would bear the bulk of this burden. I also deem that it is fair for African Americans and Native Americans to receive much of the reparations from the US. As for the Middle East, the British and French would bear the bulk of this. Returning priceless treasures, in Pakistan's case the Koh-i-Noor and the Peacock throne of the Mughal Emperor would be the first step in this process. In Iraq's case, eventually, the pieces of the old gate of Babylon, and other priceless artifacts. We are currently at square one, but eventually once the Western powers, especially the US, begins to decline, then we can force the US and other Western nations to heed our demands using International records, colonial transactions, and other information available at our disposal.
Before any of this is accomplished, however, the first two points: Non-Interference and Withdrawal of Foreign forces much be observed. Democratically elected governments must be allowed to form in all countries in the Middle East, without prejudice towards or against religion or secular. Only after these two points and the formation of representative governments in the Muslim world, can we negotiate reparations for West African countries (Ghana, Gambia, Senegal, Guinea, etc.) especially, and to a lesser degree, Middle Eastern countries, especially Palestine, Iraq, Afghanistan, and Lebanon.
Not only independence, but reconstruction is necessary to complete the transition of these nations into representative and prosperous nations. Undoubtedly, the unjust colonial adventures in the modern era will have to be paid for by the ones who reaped the most benefit from the exploitation of human beings.
