Saudi Aramco IPO - suitable for Widows and Orphans?

Does it really matter where the listing takes place? The more important question must be - given the negligable influence of public shareholders, the uncertainty over the future energy scenario and the huge political risk surrounding the Middle East region, including Saudi Arabia itself, can regulators allow this IPO to end up in the portfolios of savers and pensioners? Of course, the financial intermediaries and Saudi Arabia's oligarchy would laugh all the way to the bank!
