The CIA learned that you cannot just blow up WMD facilities. That is what the US did during the 30 day air campaign prior to Desert Storm. And the CIA discovered it created local environmental catastrophes and killed a lot of people near the facilities. So the ole WMD components have to be disposed of properly. Not just blown up. And what was probably left was held in containers that leaked and could not be safely transported. Leaking containers holding WMD are a problem even here in the US. Research Hanford and WIPP. The old Iraqi facilities needed to be guarded and the public kept away.
Yes, there is a problem with leaky containers right here, right now in West Texas.
There is no danger, so says the government.
