Turkey supports the Syrian anti-government, and many anti-government organizations are headquartered in Turkey. The United States is condemning Russia for bombing anti-government forces in the name of air strikes against IS. For Russia, anti-government or is is the enemy, not to mention the terrorists in anti-government armed forces have everything. If they blow up, they will blow up and be condemned. But for Turkey and the United States, the funds they provided were indirect bombing. Isn't that a waste of water? For Russia, the oil sold by is has seriously violated the interests of small shops. Grandsons can sell for 20 at an international price of 40, and they don't try their best to fry. Some places that lead to is can hardly start work. If there is less oil, the price will rise. Then the interests of countries that indirectly eat black oil, such as Turkey, will not be damaged. Therefore, when Turkey shoots down the Russian plane, the Russian bear will inevitably retaliate, and it cannot be a mistake.
