Turkish operation in Syria
If Russia wanted to, it could deploy three armored divisions to Syria within 72 hours and thereby permanently solve the problem of Islamist rebels. The US could do the same in its pursuit of removing Bashar al-Assad from power.
The Turkish operation in northern Syria came to a decisive point. The US Defense Department has expressed concerns that under fire from the Turkish army were Kurds from YPG units, trained and supported by US special units.
This operation in Syria is being held against the Americans' will. On the one hand, it is against ISIS while, on the other, it is also being carried out against other elements in Syria who want to divide the country along ethnic lines.
