the US has always considered chem/bio weapons to be WMD.
Well...did it? I don't think so. They didn't call them WMD back in the 70s. They called them unconventional weapons which is what they basically are.
FWIS, you can call a molehill the Rockey mountains, too, if you want ,but that does not make a molehill a mountain.
I merely gave you an illustration to make my point. Let me try again without numbers.
Let us presume we can deliver an atomic weapon weighting 10,000 lbs on manhatten.
Let us also presume we can deliver 10,000 lbs of chemical weapons on the same spot.
Now certainly both would kills thousands of people but which one would deliver MASSIVE destruction?
The nuclear weapon would kill millions of people instantly, tens of millions within days of the bomb.
The chemical weapons would kill thousands and that would be the end of it.
MASS implies something truly massive.
Comparing the destructive capacity of nuclear weapon to poison gas is merely making an enormous mistake in scale.
But okay, I'll play...what is the "killing potentiaL threshold" to become a weapon of mass destruction, in your opinion, del?
Where AND HOW do YOU draw the line in what constitutes a weapon of MASS destruction?
a properly handled M2 is a weapon of mass destruction, IMO, but generally speaking nuclear, bio,chemical and radiation weapons are what now are considered to be covered under the rubric WMD.
of course, you may disagree so here's a few other definitions for your perusal.
A weapon of mass destruction (WMD) is a weapon that can kill large numbers of humans and/or cause great damage to man-made structures (e.g. buildings), natural structures (e.g. mountains), or the biosphere in general.
The term is often used to cover several weapon types, including nuclear, biological, chemical (NBC), and radiological weapons. Additional terms used in a military context include atomic, biological, and chemical (ABC) warfare and chemical, biological, radiological, and nuclear (CBRN) warfare.

"Weapon with the capacity to inflict death and destruction indiscriminately and on a massive scale. The term has been in currency since at least 1937, when it was used to describe massed formations of bomber aircraft. Today WMDs are nuclear, biological, or chemical weapons frequently referred to collectively as NBC weapons. Efforts to control the spread of WMDs are enshrined in international agreements such as the Nuclear Non-proliferation Treaty of 1968, the Biological Weapons Convention of 1972, and the Chemical Weapons Convention of 1993. See nuclear weapon; chemical warfare; biological warfare"
