Russia and China are our real enemies. Russia is arming Iran with nukes, and China could shut down DPRK any time they chose, but they keep these puppets or clients going to drain power and money from us. Meanwhile we treat Russia & China as diplomatic “partners” who will help us solve the problems caused by Iran and DPRK!
I’m more nervous about China militarily, but Russia knows how to run circles around us diplomatically. I agree with your assessment on their relation with North Korea and Iran.
