Soaking the area in a hypochlorite solution would put out your mythical fire.
Again, the current reports say that US forces ARE checking out suspected chemical sites.
You said that they should not.
You made an excuse for them not finding anything.
That excuse was the scenario you presented. With the fire and the VX and so forth.
Yet the fact is that the US troops are doing EXACTLY what you said they should NOT do.
And they are NOT encountering your mythical fire.
Strange.
