NATO is always an American issue. NATO is powder keg idea. You don´t want the whole world converge into two camps. It is very dangerous (cf. Europe before WW1).
Imagine if Russia, China, Syria and Iran were to enter an alliance which states "if one is attacked, all are being attacked". Even though Iran and Syria would be much safer, I wouldn´t want to take this risk.
Not to mention if that alliance tried to convince Venezuela and other states in Latin America to join.
Perhaps the US would attack Venezuela and then the Russians would send billions worth of arms to Venezuela, stating on television that "the brave Venezuelians are defending our freedom"
I hear this sentence constantly on German television with regards to Ukraine.
