The relationship between the USSR and the Arab world during the cold war has nothing to do with what Arabs or Russians do with their money which was your point. Both of your oligarchs buy assets in the west.i am not sure how you came to this conclusion. Russia has always supported Arabs and Afrikan when they confronted West. start with recognition of Saudia against Europeans powers. if Stalin was not in power. US/USSR/Arab relationship history would haven been different. look at 1956 Suez crises. this alone gives Arabs leverage on Europe-Asia trade.
The reason Arab states are weak and so dependent on the west is because of the constant religious/cultural bickering. This has been capitalised on, and in some cases, exacerbated by the west and lead to decades of exploitation - the old "divide and conquer"
The situation we're currently in is quite rare, there seems to be a relative peace in the middle east. Against all expectations the Yemen ceasefire has held, and Iranian leaders are meeting with senior Gulf Arab nations. This was unthinkable a year ago.
I would attribute it to Russian diplomacy and mediation, Arabs are finally realising all they need to do to get rid of Israel and western imperialism is to stop fighting for a year or so and collaborate with Russia and China.
Done correctly the impact on the west would be seismic and would make the current western crisis seem like nothing.
Now for you to tell us something about how germanic engineering will somehow overcome that.
