Even the advanced technology part has an asterisk next to it. The majority of equipment in the US army's military is cold war era. F-15s, F-16s, Blackhawks, Abrams tanks are all from the 70s. And their logicistical platforms...LOL.
Plus all of their recent wars have been against massively unsupported enemies. Was there even a single instance in Iraq or Afghanistan of insurgents using MANPADs? No, they only faced AKs, RPGs and IEDs, and they still lost.
The next country NATO decides to invade China and Russia should give MANPADS, drones and other modern equipment to level the playing field.
