Honestly , ISIS . Assuming G . I . Joe isn ' t getting any aid from any other forces , ISIS with Cobra tech and tactics would wreck . That completely destroys the one thing keeping them in check now , no air support . Now they get near future tech , and a willingness to kill themselves in an attack . One hope I see is Cobra early on abandons ISIS cause they realize they ' re fucking psychos cause they ' re actually killing people . I imagine the first time they give them lazer blasters and they start actually aiming at people they would be out of there . The GI JoeCobra universe definitely finds loss of life abhorrent , cause they don ' t hit shit . <| sep |> Nice to know , but they all come like that from Chinese big resellers .
