I&#x27;m reminded of an article I read in one of Jerry Pournelle&#x27;s anthologies.  It was written by a Vietnamese man who had agitated against the Americans during the Vietnam war.<p>At one point, he was in jail for resisting the Americans.  His father visited him, and asked &quot;What the heck are you doing?&quot;  He answered &quot;Fighting against the oppressor Americans!&quot;  His father responded &quot;It&#x27;s true that they&#x27;re oppressors, but the communists are worse.&quot;<p>He didn&#x27;t believe his father.  When the Americans left, there was a victory parade through Hanoi.  Which was composed <i>only</i> of communist regiments.  He asked the other people involved in the resistance &quot;Where are all the non-communist regiments, which were the majority of the fighters?&quot;  The answer was &quot;On exercises in the country.&quot;<p>It turned out that the communists had infiltrated all of the non-communist resistance groups (of which there were many), and taken them over from the inside.<p>A few years later, with his life in danger from the communists, he fled Vietnam, became one of the boat people, and immigrated to America.
