After reading these posts, I decided to look for any statements, articles or books written by this "lover" of the Ottoman Empire. As often happens, in response to a request on this topic, I was recommended, among other things, the book "Strategic Vision" by Zbigniew Brzezinski. I looked through the table of contents and came across something amazingly relevant for today.
"PART III. The World After America by 2025. Not China, but Chaos
1. The Post-American Confusion
If America loses its leadership, it is unlikely that it will pass to any one successor, as most now predict for China. If a sudden, widespread crisis of the American system sets off a rapid chain reaction leading to global economic and political chaos, then America's gradual march toward increasing decline in all areas and/or an endlessly escalating war with Islam is unlikely to end even by 2025 with the "coronation" of a successor to the world throne. By then, no power will be ready to take on the role the world has assigned to the United States since the collapse of the Soviet Union in 1991. What is more likely is a long period of rather chaotic reshuffling of global and regional power, with far more losers than clear winners amid international instability and even potentially mortal threats to global well-being......»
«.......Even if America’s gradual slide into decline is uncertain and contradictory, it is possible that the leaders of the catch-up countries, including Japan, India, Russia, and some EU members, are already assessing how a potential American collapse would affect their own national interests. Indeed, it is possible that the prospects of a post-American disorder are already quietly influencing the agendas being developed in the offices of the world’s leading powers, and perhaps even current politics. Japan, wary of China’s assertive ambitions to dominate continental Asia, may be considering closer ties with Europe. Indian and Japanese leaders may be considering options for political or even military cooperation between their countries if America falls and China rises. Russia, for now mostly daydreaming (or even gloating) about the uncertain prospects of the United States, may be looking to the independent former Soviet republics as initial springboards for consolidating its geopolitical influence. Europe, which has not yet achieved homogeneity, will be torn in several directions: Germany and Italy will be drawn to Russia for commercial reasons, France and unreliable Central Europe to a more politically united EU, and Great Britain will try to find a balance within the EU, while maintaining a special relationship with the weakening US. There will also be those who will try to quickly grab a piece of the regional pie - Turkey in the territory of the former Ottoman Empire, Brazil in the Southern Hemisphere, and so on ... "
That's how Mr. Brzezinski thought. About 20-30 years ago, each of his articles was an event in the political science community, not to mention his books. His foresight is simply fantastic.
And who is this Barak? It seems that he is just a successful businessman. Well, yes, now he is an ambassador, his view on Turkey is interesting. Even more interesting is what recommendations he gives to his government

Has he written any articles or books?
He is not a political scientist. I did not continue the search, fearing disappointment: what if I stumble upon his book with a title like "How to Become a Millionaire?"

and not something like "Global Chessboard"
