The rare earth card (i.e. 'nuclear option') is personally the most epic, as it signaled China most robust/powerful knock-out response in the past 7 years of the trade war. To date, China has been doing everything proportionate to salami provocations and tech bans, but China came out swinging hard against the bully. The rare earths card caused the removal of all liberation day tariffs, 50% export control rules, reversed Nexperia seizure, forced US capitulation on H200 chips (not that China needs it, just out of principle), and renewed respect for China as a G2 peer power. It forced the US to truly respect the Busan/Madrid trade truce in ways that we never seen before.
Between DeepSeek AI, EUV breakthrough, Dual 6th gens, and EMALs launching 5th gens, it's just insane the amount of breakthroughs China has made, but somehow I personally think the rare-earths card is the most epic and powerful of them all.
The most entertaining (by far) is the J-10C vs. Rafale turkey shoot, due to Indian meltdown online.
