Geopolitics 101
People will be at each others throats and the next day they are the best of buddies until they do it again.
If the two heavyweights ( turkey and KSA ) in the middle east can get it going for good in a long shot, it will ultimately solve 80% percent of the middle east problem.
And of course, this is particularly good for bangladesh! given, maintaining the good relationship with both countries simultaneously are strategically important for BD. There was tension in the past, that made the balancing act little more complicated. But that would be no more.
For now ( after KSA and UAE ) the only sizable problem remained is EGYPT. But I have a feeling, as the things moving fast toward positive direction, it will be solved soon.
Because what unique about this time compared to the previous era is the fact that, muslim countries in general and especially the arab countries day by day gaining the ability to act more and more independently from heavy western and foreign influences. And that is a blessing!
30 years ago you wouldn't even imagine SAUDIs doing something like that, going against vital us interests. And yet now this is happening!
If middle east as 'brothers' and neighbors can solve their major issues within themselves without allowing third party at the table ( west ) to exploit their differences, it will be win win for turkey and everybody in the region. ( Expect probably for iran and israel )
I don't wanna let my imagination too wild for now but imagine if two decade later ME ( turkiye, qatar, saudi arabia, quate and UAE ) can have an integrated economic and security structure!
And i think this is achievable in along shot! Turkey has technology and other has money and energy!
An 'arranged' marriage of that two will benefit everyone immensely. And make third party ( west ) hold their tongue forever. ( and I think, like qatar very recently KSA and UAE start to understand that and learned from their past mistakes )
And for turkey explicitly, a peaceful and friendly neighborhood will allow to shift more focus on its western border ( greece in particular and the west in a broader sense ) and will enable it to project power far aboard in a significant manner than before.
