Then show everyone some credible evidences that the US cannot build rockets.
Here is something that will surprise you PDF Chinese...
The basic technology of the rocket have
NOT changed. Yes, we have made the rocket more efficient and in the process more powerful, but as a propulsion method, it has not evolved. It cannot evolve. In evolutionary terms, the rocket have reached its apex.
On the other hand, the Space Shuttle was genuinely an evolutionary vehicle. Before the Space Shuttle, we essentially throw away every spacecraft. With the Space Shuttle, we reuse it after every flight. Sure, the thing was limited and inefficient in many ways. But that is how progress is made. The first generation set the examples on what works, what does not, and what works but needs improvement.
Show everyone who matched US just by the Space Shuttle program alone...

...And not counting other scientific accomplishments like satellites and pure science research in space.
