"Yes, America can still defeat anyone on the battlefield."

In my opinion, this is not true....perhaps against a third rate military power, but the US cannot defeat a peer competitor such as the PRC or Russia on the modern battlefield simply by wishing to do so.  The US wasted so much materiel and manpower in Gulf War 2 and Afghanistan without achieving lasting results that it is no longer the "unipolar" power that it was perceived itself to be a the end of the Cold War.  This reinforces the needs for an invigorated NATO to provide for real defence of the West rather than engaging in military campaigns simply to justify its existence.   Similarly, it makes Trudeau's mindless pursuit of so called "peacekeeping" even more outdated and useless in today's dangerous world.
