defenseless because Tony decides to be Regular Man instead of Iron Man forever by depriving the earth of Iron Legions to combat threats despite the fact they break like toys and toilet paper because of true love. SHIELD is borked to shit, lost its heroes, cleared its moles and shut down and now they are unable to stand up to Thanos, Dormamu and the cosmos or HYDRA remnants and are left to The avengers, Coulson with his Interns and Nick Fury to defend it. The only reasonable line of defense would be Captain America, his best friend Falcon, War Machine and Thor when he decides to go full time on Earth and leaving Loki to play king on throne whose first order is to save the biggest whore called Lorelei for future use... man Earth is far from safe and in deep shit post Winter Soldier with the Real! Mandarin stepping his game and Baron Strucker enslaving Mutants/Gifted and Bucky/Winter Soldier in the ropes between good and evil.
