6. If you want to be really on the nose, you have the Flag Smashers kidnap the GRC, load them on helicopters, and fly them to Liberty Island, to execute them in front of the inscription of the Emma Lazarus poem, the New Colossus. As usual, they're recording, only once they have the hostages, they start livestreaming. Sam can fight Batroc, and Bucky deals with other super soldiers (with John Walker not getting any sort of moment of redemption; he just doesn't show up except in the epilogue). Then when the choppers fly, Sam can do the same trick where he kicks a guy out and then has a hostage take over flying; but one of the choppers makes it to Liberty Island.
And that's when Sam lands and talks the situation through, winning by deescalating the situation. Some other helicopters are around...
