We have our own civil war with two sides of Captain America. The first being the failed release of his 1990 adventure which ended up making its way direct to video in 1992. The much higher budgeted Marvel Cinematic Universe version in 2011 introduced Cap as The First Avenger and was the last solo MCU film before a little arthouse success in Joss Whedon's Avengers the following year. This one isn't much of a debate, so we bring in Master Sergeant Bill Paxton as a true threat to the guy wielding the shield.
