The Art Newspaper and "Culture Grrl" have been generally supportive of repatriation efforts, but each has expressed some misgivings about the recently announced MOU with Greece. See http://www.theartnewspaper.com/articles/Clinton+signs+memorandum+with+Greece+restricting+import+of+antiquities/24369
and http://www.artsjournal.com/culturegrrl/2011/07/greek_cultural-property_agreem.html
And no wonder. The articles point to the lack of transparency, the apparent overbreath of the coming restrictions and Greece's own abysmal record in protecting its own cultural patrimony.
They might have also mentioned that approximately 70% of the public comment posted on the regulations.gov website either opposed the MOU in toto or the extension of import restrictions to coins.
Apparently, Secretary Clinton considers "confidence building measures" for the bankrupt Greeks to be more important than the views of American citizens or the legal limitations the governing statute places on such MOUs. But does the ordinary Greek citizen really care? See http://safecorner.savingantiquities.org/2011/07/repatriation-effects-greeces-national.html
And what will American voters who collect ancient art and coins think about these new restrictions? The ever political Hillary Clinton should also consider that as well.
