The Two Civil War Teams Will Initially Battle Thanos Separately

This year, Captain America: Civil War will split the Avengers right down the middle, as Captain America and Iron Man lead two teams with opposing views over the implementation of the Sokovia Accords (a legislative bill that requires superheroes to register as such).
It’s generally expected that the two sides will set their differences aside in order to combat the threat of Thanos in the Avengers: Infinity War movies, but one rumour suggests that won’t be the case at all – at least not initially.
It has been suggested that the two Civil War sides will attempt to fight the Mad Titan separately in the first movie, before realising they need to work together to combat him in the second movie. Whether or not that’s actually the case remains to be seen.
