From the Schock Press Release:
“Iran is a regime that has used every weapon it has ever acquired,” said Schock. “I do not intend to go to Congress and sit idly by while Iran gets nuclear weapons. This is a grave threat to our country and it requires tough diplomatic strategy to resolve peacefully without an invasion or war.”
This is perhaps the most misleading statement in a statement full of garbage. Iran has never utilized biological or chemical weapons. In fact, it was entitled to use chemical weapons against Iraq when Iraq used them against Iran, but Iran refused and condemned Iraq for using such weapons and then joined the Chemical Weapons Convention in the 1990s.
Furthermore, no one has alleged Iran is trying to develop biological weapons despite the technological ability and the infrastructure existing to do that since Iran has advanced biological research facilities.
There is some question as to whether Iran has sought technologies for these weapons, but most of that centered on being prepared for another attack by Iraq.
So they have only utilized traditional weapons, not WMDs. Suggesting they have utilized such weapons is misleading and one might conclude, a purposeful lie.
