In short. the U.N. has completely ignored the basic legal requirement for coming to agreement. namely. that there be unanimous acceptance of all conditions imposed by both sides. Without such mutual acceptance. no agreement can be legally binding. There is no Headquarters Site Agreement in force today. There Is no legal requirement that we grant visas to the Vietcong. or to any other subversive elements which we wish to exclude from our soil. In this new light. therefore. the U.S. policy of inviting the Vietcong to come to America is revealed as an entirely gratuitous action. We certainly have no moral requirement to invite our enemies within our gates. and we have no legal requirement.
