Binance and Tether are nowhere near big enough to be major financial weapons against the west. They also have nowhere near the sort of supposed major government or criminal support from anyone interested or powerful enough to stop their possible collapse. That you're claiming they do is odd compared to many, many other more mainstream financial systems that have been used as tools by governments and criminals for a lot longer than crypto has even existed. People could have claimed something similar to what you say about FTX just months ago, and would have, as we now know, been very wrong.

Edit: Just the daily trading volume of, say, the forex market, completely dwarfs both the total market cap of tether or the daily volume of Binance. The total value of global equity trading worldwide is also insanely bigger than these two combined.
