UNDER INTERNATIONAL LAW, IT IS ILLEGAL TO ATTACK ANOTHER COUNTRY WITHOUT U.N. RESOLUTION

Under settled concepts of international law, it is illegal for one country to attack another by invading its territorial space. When Colombia under Uribe attacked a FARC camp within Ecuador two years ago, that was illegal, notwithstanding Condoleeza Rice's imprimatur. And now some believe that Israel's war planes attacked and killed two men in a Hyundai within Sudan. If so, it too violates the law of nations.
