This is an "apples and oranges" comparison, since the daft-dodgers were American citizens from the get-go. But the answer to your question is "yes". I served. They can serve. Or leave and stay gone. No free lunch for cowardice.
"What if part of this 'amnesty' requires everyone to get in line AFTER those already seeking legal status the right way?"
I oppose amnesty under any and all conditions. No reward for breaking the law. Is that really so hard to understand?
By the way, you can stop putting the word "amnesty" in quotes, because amnesty is what is being discussed here. Any pretense otherwise is pure sophism.
O.K., how about "amnesty with added paperwork" then? Would that make you happy? Probably not, because you really seem so upset about "BREAKING THE LAW" - would you be as upset if the feds and States suddently repealed the speed limit and a bunch of WHITE people, who had pending speeding tickets, got amnesty (with or without paperwork)?
