That was 150 years ago.
Russia has the ability to take out every power plant, water purification center, dam, highway junction and railway bridge in Turkey within a week, without a single Russian soldier needing to set foot there. Erdogan knows that.
The Russians would not try to invade or occupy, they learned that lesson in Afghanistan. They would simply turn Turkey into Afghanistan, then walk away.
That’s impossible. Despite turbulent past Turkey and Russia has very special relations since 1990s.
About 5 million Russian tourists are coming to Turkey every year, a great number of retirees are living there. A million of Turkish citizens work in Russian construction industry. Two of three oranges and tomatoes are coming to Russia from Turkey.
