The airlines are responsible to check. Thus you are not being denied entry into the US. You are simply denied boarding on foreign soil. Many people were trapped for weeks/months when borders closed last year. The airline would risk a large penalty for each person boarded without a verified negative test. The airlines lobbied for this so we can hope they have a testing plan ready to go to actually implement it...LOL.
