The Middle East isn’t divided by the US, it’s divided by its own history of imperialism, colonization, oppression and violence based on religious and ethnic lines accross the centuries. There’s really no incentive for the US keep the Middle East divided, not to mention that oil producing countries are already united through OPEC.
Ahh yes. The Middle Easts own history. Clearly has nothing to do with French, British or US being the colonizing entities... And after all why would the US be interested in dividing a region that is connecting 3 continents and has the mos accessible of the main strategic ressources of the past two centuries.
And of course all the plans of the US that specifically talked about destroying nations like Iraq and Syria and the invasion of Iraq to do exactly that... All coincidences! Who would be so mean to assume this to be part of larger strategies?
