Is it not the sworn duty of congressmen and senators to uphold the constitution? and in there is there not an oath to preserve and protect that law? As well as the land?
If congress has no business in international treaties, why the **** does the constitution say they have to be ratified?
Now to the point. It is misleading by degrees of magnitude to suggest that neither members of the house nor senate are ignorant of the details of negotiations; if so Obama is derelict in his duties, as Netanyahu knew, down to the nth detail, Canada has known ans has been objecting and Iran knows what is proposed, their REJECTION was to the point and specific.
So what you have is Iran hates it, Canada hates it, Israel hates it, but Obama still wants it and is now blaming congress for doing the job HE should be doing as Chief of the Executive branch.
So, as they say, what specifically is your point? Are are you pouting because another one of Obama stupid ideas has been shot down by a few hundred wiser men?
