#bosphorus strait

🇹🇷: <knocking at the door> Sweetie let me in!

🇪🇺: No!

🇹🇷: Babe let me in!

🇪🇺: Absolutely no!

🇹🇷: Ah come on let me in!

🇪🇺: No God damnit!

🇹🇷: <sigh> whatever man... *looks around*

🇷🇺: *sitting at a street corner playing harmonica*

🇹🇷: Aye girl nice to see ya. How ya doing? Can we hang around somewhere nearby? Your choice. Let us exchange phone numbers too if you feel good enough.

🇷🇺: *reciprocates albeit silently*

🇪🇺: <screaming out the window> HOW DARE YOU!

That is a pretty spot on summary of the last few decades of Eurasian geopolitics. It is essentially the world’s longest running, most stressful romantic comedy where nobody actually ends up together and everyone is constantly checking their "Ex’s" social media. Here is the "behind the scenes" of the drama you just described:

💔 The Perpetual "Waiting Room" (🇹🇷 & 🇪🇺)

Turkey 🇹🇷 has been knocking on the doors of EU 🇪🇺 since the late 1990s. While they are technically an official candidate the relationship has hit major roadblocks:

The "It Is Complicated" Phase: Issues ranging from human rights and judicial independence to the status of Cyprus 🇨🇾 have kept the door firmly locked.

The Tired Rejection: The EU 🇪🇺 often feels Turkey 🇹🇷 is moving away from European standards while the Turks feels like they are being given a permanent "maybe next time" just to keep them in the neighborhood.

🪗 The Pragmatic Rebound (🇹🇷 & 🇷🇺)

When the EU 🇪🇺 says "No" Turkey 🇹🇷 often turns East. Their relationship with Russia 🇷🇺 is what diplomats call "adversarial collaboration".

The Harmonica Vibes: They do not always agree (eg Syria, Libya 🇱🇾, Iran, Ukraine 🇺🇦) but they are experts at sitting on that street corner together to trade energy, S400 missile systems and tourism deals.

The "Phone Number" Exchange: It is more about showing the West that Turkey 🇹🇷 has other options.

🪟 The View From The Window (🇪🇺 Reaction)

The EU's "How dare you!" is not just jealousy but a major security anxiety.

The NATO Twist: Turkey 🇹🇷 is a key NATO member to the point where it has the second largest number of active duty troops in NATO. Seeing them "exchange numbers" with Russia 🇷🇺 makes the EU 🇪🇺 (and the USA 🇺🇸) incredibly nervous about the unity of the West.

The Leverage: Turkey 🇹🇷 knows that every time they lean towards Russia 🇷🇺 the EU 🇪🇺 gets desperate to keep them in the fold even if they will not let them through the front door. If geopolitics were a reality show, this episode would be named "The S400 and The Cold Shoulder".

"If only 🇹🇷 shut down the Bosphorus and banned all naval access to 🇪🇺"

That would be the geopolitical equivalent of Turkey 🇹🇷 not just slamming the door on the EU 🇪🇺 but also building a brick wall in the middle of the hallway and charging a "viewing fee" to look at it.

If Turkey 🇹🇷 actually shut down the Bosphorus (the Istanbul Strait) and the Dardanelles to EU 🇪🇺 naval access we would not just be looking at a "breakup" but also at a global systemic meltdown. Here is what that "Total Blockade" scenario would actually look like:

01. The Legal Nightmare (The Montreux Convention)

Since 1936 the Montreux Convention has governed the Bosphorus Straits. It basically says Turkey 🇹🇷 has the keys to the house but they must let merchant ships through during peacetime.

The Violation: If Turkey 🇹🇷 unilaterally blocked the EU 🇪🇺 they would be tearing up one of the most stable international treaties in history.

The "Wartime" Loophole: Turkey 🇹🇷 can technically close the straits to warships if they feel "threatened by an imminent danger of war". Closing it to all naval access (including trade) for the EU 🇪🇺 would be Turkey 🇹🇷 declaring that the EU 🇪🇺 is an enemy combatant.

02. "Friendly Fire" (Bulgaria 🇧🇬 & Romania 🇷🇴)

This is where it is awkward. Bulgaria 🇧🇬 and Romania 🇷🇴 are both:

Full members of the EU.

Full members of NATO (Turkey’s own military alliance).

Located on the Black Sea.

By blocking "the EU 🇪🇺" thus Turkey 🇹🇷 would effectively be blockading its own NATO allies. This would likely trigger Article 4 (consultation) or even Article 5 (collective defense) of the NATO treaty. The rest of the alliance would see Turks "holding the family hostage".

03. Economic Mutually Assured Destruction

Turkey 🇹🇷 and the EU 🇪🇺 are massive trading partners.

The EU's Pain: Massive disruption to grain, oil and gas flowing out of the Black Sea. Prices for bread and fuel in Europe 🇪🇺 would skyrocket overnight.

Turkey's Pain: The Turkish Lira would likely enter a freefall. The EU 🇪🇺 is Turkey’s largest export market. If the EU 🇪🇺 retaliated with a total trade embargo the Turkish economy would face a crisis unlike anything it has seen in the modern era.

04. The "Russia 🇷🇺" Complication

If Turkey 🇹🇷 blocks the EU 🇪🇺 but keeps the door open for Russia 🇷🇺 it would be the ultimate "choosing a side" moment. The Turks currently balance both sides (the "harmonica" scenario). Closing the door on the EU 🇪🇺 would mean Turkey 🇹🇷 is now fully "all in" with the East thus losing all leverage as a bridge between two worlds.
