Iraq should not exist. It and Saudi Arabia are made up nations from their origin, the never ending “gift” of western intervention into the Mideast.
Saudi Arabia was not put together by the Western powers and was never under their rule.
King Saud conquered most of the Arabian peninsula tribes and actually exiled from Jeddah the Hashemite’s to Damascus from which they were ejected to Jordan
Syria and Iraq were cobbled together by the English and French, yes.
however, this "intervention" was post-WWI when the Ottoman Empire collapsed.
IF the BRits and French hadn't stuck their noses in then, there would have been a bloody ethnic war in 1920 -- that was just delayed by 90 years...
