It is pretty easy to put on an impressive parade when you have a military of 2 million people and aren't a global power vs the US with 1.3m and have bases all over the globe. Even Russia was able to put on a bigger parade while they were fighting Ukraine and had lost tens of thousands of soldiers.
The parade was pretty paltry, but the fireworks display was very ostentatious. Breaking out the vintage stuff was cool, but lame that they didn't at least put some mock .50s on the half track.
