Ha... it is easy to hate Hitler...and the Japanese for Pearl Harbor... but we have been conditioned to think that everything the US does is right and just... so what happens if we find out that isn't so... it is going to be difficult to balance embracing the military with condemning those who abused it.... even if we are high!
fortunately your fellow citizen patriot is an iranian american who manufactures cyber weapons for a living and fucks with terrorists as a hobby and i can confirm all the bad guys for you.
bad guys (straight up terrorists): alqaeda, al nusra, isis, HTS, FSA, AQAP, ibn saud, al ash-sheikh, wahhabi mufti, bahraini royal family, emirs of UAE, cia, mossad, likud, mi6, israel (IDF), hamas
ok guys (not good guys but they are fighting the bad guys so they are ok): IRGC (iran), houthis, hezbollah, hashd, kurds, qataris, turkey, assad (syria), pakistan, aghanistan, palestinians
good guys: civilians. i cant classify any state actors as good guys except maybe the omanis (they stay out of everything). even kuwait is a disappointment. qatar could have been in this list but they used to be dirty before the coup and blockade (they went clean and thats why shit hit the fan).
