There has been too much secrecy insofar as Southeast Asia is concerned. and there still is too much secrecy. in my opinion. covering operations in the old Indochinese States of Laos. Cambodia. and South Vietnam. as well as in Thailand. The Senator makes reference to the defoliation. I have read in the newspapers that the effect of defoliation will last 100 years. He did not mention it at this time. but he has mentioned previously the refugee problem which now embraces millions in the three Indochinese States. The Senator from Iowa has spoken previously about the drug culture out of Vietnam which was transplanted here. I think that while we always will remember the illadvised tragedy which was our involvement In Southeast Asia.
