I am not sure this means much. Isn't this what all militaries do? They prepare to fight the most likely enemy they may face? I believe the US Marines built a full-sized mock-up of a Chinese stealth strike fighter.

My bigger concern is how certain people on the right will try to use this for domestic propaganda against the Biden admin. It doesn't matter if their claims do not make any sense and if they can easily be disputed and shown to be illogical, the fact remains that it's the red meat their base wants and will eat up without question. Which seems like a huge win for China, because it means that if there ever is a serious real threat posed by China or any other nation, we're not a serious enough country to deal with it..
