The main reason why russia did not send special forces into Turkey is that Turkey is a member of NATO. I watched the russian TV video about the shot down plane where russian politic stated that if Turkey was not in NATO, our forces would be in Istanbul next day. Putin and russians are cowards. He can only kill weak ukrainins and syrians. When it comes to NATO member he craps his pants.
Does NATO means Turkey can shoot down Russian jet and later the pilots are killed mid-air because of Turkey airforce actions ?
or Russia does not want to risk war with NATO ?
There will be no war of Russia with NATO, even when Russia starts annexing the Baltic countries. Such war is likely to grow into a full-scale nuclear war, which means that everyone will lose.
