When that American is fighting in a foreign force and aiding actively against US/alied armed forces as a combatant? Yeah I think that’s okay. You can’t hold off on a military target because some American mercenary is there. Those are the chances you take as a mercenary. We’re discussing a president who can now kill anyone he wants with Seal Team 6 and not face any repercussions ever, unless impeached, well I hate to say it but the current MAGA party will never impeach Trump under any circumstances.
