You’re right except it wasn’t executive order——it was the Arms Import/Export Control Act (sp). Bush 41 started the big double cross with respect to firearms. I believed at the time that he had no freeekin idea what he was signing.
Barack Obama is reportedly going to sign the treaty this month while Congress is on vacation.
