First of all, the 2010 incident of China withholding rare earths from Japan is a textbook example of success as it got the fishermen returned in days. It was only a failure if you thought that the purpose was to permanently cripple Japanese electronics manufacturing.Why am I sceptical? I don't have a clear picture how China plans to implement this, without antagonizing bystanders. They would have to enforce a serious crackdown on the black market and shutdown all Alibaba entities selling rare earth or rare earth compounds to begin with.
Then they would need to police the world market to ensure the US cannot source it's need from intermediary sellers. Effectively they need to lower their export quota by the amount the US imports, if they can estimate that right. However, according to:
the US imported 100% more rare earth's in 2018 than in 2017. Quite obviously a stockpiling measure. That alone gives them a year worth of supply. The unknown is how fast can they get the refinement facilities up and running to process the ore from US and Australian mines to weather a long term decoupling. Also, not to discount are recycling initiatives. There's plenty of this stuff in junk electronics
So the link you posted shows no stockpiling of rare earth compounds or ferocerium alloys but a 91% increase in scandium and yytrium. Then we must also account for the fact that America's need for these elements has been steadily rising by an average of 15% a year from 2014 and 2017. If that trend continues, then we can approximate that the need for them in 2018 was close to 602 metric tons and in 2019, the need should be about 693 metric tons. If the US purchased 1000 metric tons in 2018, that leaves a 398 metric ton stockpile. We don't know what purchases in 2019 look like yet, but this is so far looking more like a 6-7 month stockpile than a 1 year stockpile.
Then we have to talk about recycling. First of all, America's been sending a lot of its recyclables to other countries, including China, so there's not likely to be as much around as you surmise. Then, I researched briefly the current technologies associated with recycling rare earths and it seems that the technology is still lacking a lot of research so its cost effectiveness and efficiency is too low to do on mass scale. Currently less than 1% of electronics have had their rare earths scavenged. According to this peer-reviewed scientific article published October 2018, (abstract only; the rest you need to pay), which has a very rosy take on the future of rare earth recycling, the technology is still quite unreliable/unavailable.
And it's not about total denial of America's rare earth supply. It will severely hamper the efforts to get them and constrict the supply causing great stress on the reliant industries in the short term but in 1-3 years, the US will be able to get its own processes up and running. Therefore, if China uses its rare earths card, it's going to be a one shot thing, but one shot could be all it needs since the US is out of cards after a tech ban but China is right on the verge of an overtake and stunting the US by 2 years (which is really a huge across-the-board blow to tech industries) could get China a heads into the lead from which it will never look back again.
Now do I think this card will be used? No. Why? Because China's talking about it. The more you talk about, the more heads-up you give your opponent. If China wanted to use this card, it should implement the ban without any warning at all. DOW would go underwater overnight and Larry Kudlow would be holding up chunks of iron on national TV telling people that this is rare earth and all we need; everybody it's ok, put your money back in the stocks LOL. This advertising here seems to point to a different strategy, which might be to sink US scientific efforts into developing its own rare earths refineries and money into stockpiling only to undercut in a year and wipe the fruits of these efforts out. Just a guess.
