Okay, you have Optimus and the autobots working with NEST to root ant decepticons and stop further attacks. But I just thought of something. First, he doesn't share the Weapons tech. Sure it would be dangerous if it fell into the wrong hands, but imagine if some robot like Devastator was unleashed in a populated city. With no way to stop it. And wouldn't it be beneficial to try and foster relationships with other countries and base autobots there? I'm not sure going to a country, defeating a big decepticon, and leaving the cover story that it was a big toxic spill would be good relations with the public. Would it hurt the guy to make a few public appearences instead of throwing out these cover stories?
