The US sold Saddam Hussein chemical weapons to kill Iranian civilians.

This is no more than racist rant.

First, lots (perhaps more than Chinese) those workers are from other South East Asia countries where bats are rampant and the coronavirus may have originated from.

Second, that these laborers are Chinese imply nothing. Given the Italian sewage from 12/18 was tested positive, that would imply rather widespread of the virus in the area and so the virus was likely there long before December. It is equally likely that people, maybe these Chinese laborers, brought the virus from Italy to China.

Are you really saying that, despite a long history of lies and cover-ups on major matters from the US government, in this particular instance (right before the COVID-19 outbreak) they did their very best to be open and transparent with other nations, the exact opposite of what they've always done in the past?

Based on satellite image analysis? We tried that 20 years ago. How accurate was that?

Given that the Italian sewage from 12/18 and French man sample from 12/27 were tested positive, what make you think there couldn't be cases in August in Europe?

Given that cases occurred in December in these two countries and yet they didn't report their cases until February, and that's long after the Chinese reported their first case, what make you think the Chinese must have identified any new disease earlier than December?

Given the Chinese whistle blowers reported their findings between 12/27 and 12/30, if there were widespread outbreaks in China much earlier, why didn't they blow their whistles earlier? Maybe your next conspiracy theory is that those are not real whistle blowers but Chinese government actors acting like whistle blowers for some evil agenda.

Last I checked, the Chinese don't have time travel or prophesy capability
