You guys need to calm down...
Firstly I don't trust the Europeans or Americans. They've backed terrorists and subversive religious organizations in Türkiye for decades.
With that said, the west as a whole is in decline. The good times are over, and whilst quality of life in the west will be superior to most of the world for decades to come, they've reached the limits of their power.
For years NGOs, bought out politicians and lobby groups have been accelerating the decline of the west. They've been pushing LGBT, mass immigration and a number of other malevolent agendas. Now the west is slowly transforming into what the Muslim world has been for the past 50 or so years. You'll see reactionary movements accross the west, and no this won't revive their power, if anything it'll sow the seeds of chaos.
Europe is weak, the US is incapable and hated by most of the world, meanwhile the youth in the west are as a whole sick of Israeli influence in their own countries. They're looking for new partners and Türkiye stands out as the best option. Does this mean we must accommodate them? No. But this "Decolonization Forum" is just stupid and bad PR. It's no different than the people in the US demanding that Türkiye return to the treaty of Sevres.
By the way, if you're saying "Cairo, Riyad, etc. are going to be new centers of technology and culture" I truly question your intelligence. The second oil money is gone a mass exodus will happen, why do you think Saudis and Qataris are snapping up property in Türkiye? Also this obsession with combining Turks, Arabs and Kurds as one is another agenda I'm not fond of, these people are as a whole a burden, they hate Turks, and Arabs in particular see us as "Mawali". I can see deepening cooperation with Syria and Iraq, but they'll back stab as as they've done before.
Türkiye should neither be striving to fit into the west, nor should it be choked by Arabic influence. We have our own unique culture, history and linguistic family, and ultimately we need to carve our own path instead of being foot soliders for Westerners or Arabs.
To some it up, we're low on the list of enemies of the West right now. Hell, Israel and Jewish influence is probably seen as big of a threat as China is. Why the hell are we causing a diversion when all we needed to do is sit back? The posts about this "Decolonization Forum" are going viral, very suspicious.
