Which action did carter take towards those who had evaded the Vietnam draft?

He pardoned them

Since draft dodging was illegal and many people even fled to Canada to avoid going to war or being prosecuted, Jimmy Carter pardoned all those who evaded their draft and they could return home. Out of all the draft dodgers, it is believed that only 4% actually got convicted, and conviction didn't last long because of the pardon.

He offered them a full pardon
