Technically, the SC has always applied "strict scrutiny" to such rights and the question of whether they can be removed.
The key clause on our point in the decision, cited from the Riggs case is:
It would not be contended that [the acceptance of a treaty as the law of the land] extends so far as to authorize what the Constitution forbids, or a change in the character of the [354 U.S. 1, 18] government or in that of one of the States, or a cession of any portion of the territory of the latter, without its consent."
In essence, the statement divides the constitution into fundamental and less-than-fundamental structures. It is a distinction that is impossible to maintain, as witness the recent SC decision on capital punishment where Kennedy borrowed foreign precedents. The Reid case and its relatives are not, I suspect, controlling in terms of treaties. I still would like to see the Bricker amendment passed. I will, however, say that I did not give any hint of subtlety in my response and maybe I should have. You are making a good argument; I just don't think it is sufficient to override the SC's use of the Geneva convention today. Well, I hope that this is coherent and thank you for a brisk exchange.
