If anyone is flinching in fear, it would NOT be Tony
There was a scenario online suggesting that if the full Avengers team had gotten back together after Civil War, Tony would flinch away from Steve if Steve gestured. As usual, the prop-Tony folks ignore the fact that no one was actually going after Tony. Steve was defending himself and protecting Bucky. If Tony had ever STOPPED attacking, the fight would be over. They also ignore other people's trauma: Tony shooting Sam, Steve, and Bucky when they were unarmed. All of THEM are more likely to flinch than Tony, especially because Tony had no reason to assault any of them other than his own lack of self-control. (Wanda would likely also flinch after her experience on the Raft, helpless in a straight jacket and shock collar.)

Tony didn't appreciate having to haul himself, Vision, and Rhodey to Nigeria. But even he could admit that Cap and the others had no reason to trust the U.N.'s declaration that the Accords would soon be abolished. If he was a wanted fugitive, he'd insist on meeting someplace that hadn't signed the Accords too.
When it was all going down, it never occurred to him to wonder why Nigeria had refused to sign--after all, THEY were the ones who'd had a building blown up. Apparently these folks realized that it was the bomber who was responsible for the bomb, not the hero who tried to keep it from killing a marketplace full of people.
Tony wondered how different the world would be if HE'D made the same connection between Ultron and Charlie Spencer.
He sighed and shook his head. What was important was that the U.N. was now asking the Avengers (all of them) for help in crafting the "oversight with safeguards" that Cap had asked for from the beginning.
The others were having what sounded like a serious debate, but was actually a heated discussion about yams versus sweet potatoes.
Tony flung his hands up and said, "Okay, let's get down to business."
He froze as he finished speaking. Wilson and the Witch had ducked so far to the side they were under the table. Cap had jerked forward as if to get between Tony and the others.
The room was very quiet as Tony met Rhodey's eyes. Rhodey knew that occasionally Tony dreamed of Cap stopping Tony's rampage with the slam of his shield into the arc reactor.
Rhodey also knew that Tony much more often was awakened by nightmares of breaking Wilson's neck at the airfield, or actually landing a killing blow on Barnes or Cap.
Or the very real dreams of abandoning Maximoff on the Raft and cutting off Barnes' arm.
He hadn't asked about Barnes. Couldn't bring himself to.
Tony knew he wasn't the only one suffering. He didn't like to think of how he might be starring in the others' nightmares.
Then a warm touch on Tony's arms caught his attention. He looked at Romanov and Rogers on either side, gently lowering his arms from what he realized was the same position he used when firing his repulsors. Each of them gave him a small squeeze before letting go.
He nodded at each of them as Wilson and Maxi--Sam and Wanda--sat up straight again.
Tony knew that they all needed time to heal. They would all need to be careful of each other for awhile.
He could do that. He folded his hands as Cap said, "Let's get started."
