Senator Jas,
I would like your opinion on this. I intended for it to occur and the list of nations will become the new Sec. 4, however, after passage might work as well. As an experienced senator whose opinion I value, what do you think?
I understand what you are trying to do by section 4, but I don't believe it is viable. Section 4 is not applicable until after the bill becomes law, but by then it is already too late - something of a paradox. There is no way of limiting the number of amendments a Senator can propose, without altering Senate procedures - which would be both a time consuming process and likely doomed to fail. In trying to put in a list after the Act passes, the countries involved will already have been granted free trade by virtue of the Act - something that would obviously create increased opposition to the bill.
If you wish to exclude certain countries from the effect of this bill, you should immediately bring an amendment striking section 4 and replacing it with a declared list of states to be so excluded. Senators could then suggest nations to be added and voted on simultaneously, similarly to how multiple amendments have been dealt with recently.
I will say outright though that I believe the prospects of this bill to be quite poor. A very similar bill was introduced during the free trade wave some time ago and received short shrift.
