>>22513150China or Europe just need to make one surprising move to make the situation look more serious.
Like, China could officially announce it will start reducing its holdings of US bonds because it wants to avoid losing money when their value decreases due to the falling dollar. Just a business decision.
Europe could ban US cloud and software from government computers, until the US officially declares it will not try to get Greenland. Just a security measure to prevent US getting intelligence about joint efforts to defend Denmark from US aggression.
