P.S. on Colombia/Ecuador

Anyone whose interest's been piqued by posts on counterrorism activities in Colombia and Ecuador -- which IntLawGrrl Naomi Norberg criticized yesterday and for which Luz Estella Nagle articulated possible justifications in an April guest-post -- will want to look at a recent ASIL Insight on the subject.
The author is Tatiana Weisberg, formerly an Associate Professor of International Law at the Catholic University of Minas Gerais, Brazil, and now an LL.M. student at the Center for Advanced Legal Studies, Buchman Faculty of Law, Tel Aviv University, Israel. Her Insight focuses on the March 5, 2008, resolution by the Permanent Council of the Organization of American States that Colombia's entry into Ecuador a week earlier

constitutes a violation of the sovereignty and territorial integrity of Ecuador and of principles of international law ...

With some understatement, Weisberg observes that the OAS resolution "is in tension with the declared policy and practice on this issue of the United States, an OAS Member State, and with the UN Security Council’s post-September 11th willingness to consider that terrorist violence can trigger the right to use force in self-defense."
