Yes they did, under the supposed pretext that chemical weapons might prove to be more humane. Much like Bush's recent argument that abandoning the ABM treaty might lead to a safer world. Can't complain much about Pakistan India or North Korea testing long range missiles right after you argue that you shouldn't be asked to restrict their testing.

I am not sure but I believe the only chemical weapons agreement we ever signed was in 1972 when we agreed to dispose of the munitions we had built. 30 years later we have just begun this process.
