Exactly how many traitors did Lincoln have shot without benefit of a trial?
General comment: When one bears arms against the US (not just the government, but the nation) they , regardless of citizenship, become targets, law enforcement and/or military (dependent on location).
Sometimes these targets are caught, sometimes they are destroyed by high order detonations, etc. The ones who are caught, become illegal combatants (not POWS), criminals and otherwise sorry examples of the detritus of humanity.
To disagree with the administration is one thing, to actively undertake the violent overthrow of the nation, the government and our way of life, makes one regardless of citizenship a criminal.
I had great respect for the uniformed enemies of our nation that I met on the field of battle. None whatsoever for “insurgents” and I did not ask prior to targeting them with small arms or standoff systems what their citizenship was. We indeed discovered that many of them carried passports from places like Canada, Great Britain, Norway, Eastern European nations, all of the mid eastern nations and Asia. They ran to the guns in IRQ and AFG, we dealt with them there, thank goodness!
If an American desires to change things, he becomes a voter, an activist, a lobbyist a grassroots organizer to sway opinion, not a person who directs and or participates in the destruction of office buildings or aircraft, or the raising of resources (fiscal, human or material etc) for that cause. Doing so is unacceptable, except when a long train of abuses demonstrating a pattern of tyranny is clearly and obviously apparent. The case must be made out legally, as in our founders’ Declaration of Independence. Indeed, they clearly stated that suffering until the systematic deprivation of representative government was certain and unequivocally proven, that rebellion was necessary and even moral.
The character in this discussion made none of those claims, he rather waged illegal war against the people of the US. I speak solely of the case against him, and no other, as each situation must be examined in its own merits.
Lincoln didn't have any combatant to deal with in Yemen, nor to my knowledge, anyone outside of the US that bore a threat to an American citizen.
