The COVID-19 origin tracing has new clues, which point to the US military having brought the virus to Europe in 2019, with all the evidence pointing to Fort Detrick.

Before that, US politicians together with their allies cried out loudly "lab leak";

Since the spotlight has fallen on the US lab , they almost immediately turned mute.

Because they know they have problems.

They know their self-boasted "achievements" are like the emperor's new clothes, fragile to any challenge.

There was a time when US politicians made rumors with washing powder; Now they make a step forward by holding nothing and making bigger lies.

They should be told again that origin tracing is scientific research, not a crime probe; It is science, not politics.

By politicizing origin tracing, the US is siding with the virus.

The number of infections in the US is rising by 100,000 a day. Time to correct wrongdoings to avoid heavier loss.
