Russia has very sophisticated anti-satellite missiles. Also, Russia and China both have no qualms about using nukes.
Don't confuse me with a Russian apologist, but I could not ignore that statement. I grew up with the cold war with drills hiding under desks and cubbies, but no country has used a nuclear device in anger in over 60 years. That was not by mistake, lots of resources throughout the world have been devoted to preventing that.
I have no doubt that Russia or China may harbor a desire to use a nuclear device if they could avoid direct blame. That I believe is what drives Russia to stir up the hornets nest in the middle east. They would love to be in the shadows while Iran uses a nuke.
