The Russian reaction depends on the reaction of the United States and the European Union. At his press conference Putin said annexation is not an option for Russia. I think he is waiting to see what happens. If you want Russia to be more aggressive, please, behave more aggressively to Russia.
Certainly, the two are not on the same page in Syria and some other Middle Eastern matters; they have historically adversarial relations in the South Caucasus; and they have a conflicting modern record of Turkish support for Islamist and nationalist movements in the North Caucasus. But be it bilateral trade relations or pipeline geopolitics, instead of keeping in line with its NATO allies Turkey is more savvy in following its own national interests than many Western diplomats and analysts would like to think.
Meanwhile, Western politicians have interpreted the authorization vote and the action in Crimea somewhat differently than Russian experts. So far, however, Russian authorities have been unmoved by threats of sanctions and visa bans, possibly because the stakes of backing down on Ukraine at the request of Western governments are higher than staying the course, as long as a full-scale war can be avoided.
A more realistic view is that there were some agreements between the opposition and the West, for example, not to cross certain red lines. Moscow’s position was clear from the very beginning. Russia strictly relied on the principles of international law, reminding everyone that in democratic countries people’s attitude toward authority should be expressed not with Molotov cocktails but through the ballot box.
