Are you of the opinion that international agreements that bind the United States of America are "treaties" or some other kind of document?
The article makes it clear that the founders intended that any agreement with a foreign country or a bunch of foreign countries that would bind the United States (there's 50 of them today) would need 2/3 of the Senate to approve.
Do you have a problem with that requirement?
there actually are 57 states today
Obama has so informed us
Get with the program!
(note: there happen to be exactly 57 states and terrorist organizations in the international Islamic conference/organization. a pure coincidence, no doubt...)

Treaties among nations involve such things as military agreements, navigation and rites of passage, treatment of foreigners while residing or sojourning abroad, etc.
Commercial or trade agreements are never considered as treaties because they involve revenues in the form of tariffs and only the House can originate revenue bills thereby rendering trade agreements as legislation, not treaties.
This is foundational law in the United States. Trade is never considered in the context of treaty making.
