NATO has long been involved, but both sides keep it unspoken and do not state it clearly.

Some netizens believe that from a purely military perspective, if the Russian army directly engages in military conflict with NATO, it is highly likely that they will be beaten badly. Based on the latest combat methods of the Russian army on the Russia-Ukraine battlefield, once they encounter real NATO troops, there will basically be no chance to fight back; this is not a fair battle at all, but rather a one-sided failure.
