If you can’t wait for the next installment of Marvel’s delayed big cross-over event then just pick up a trade copy of Captain America’s 1970’s battle against the Secret Empire, as written by Steve Engelhart.
The classic Cap arc just seems to me to be wholly recycled, updated a bit and turned into Civil War by Bendis and Marvel, anyhow. May as well get some 70’s Marvel goodness while you wait. Plus, in the Secret Empire story Nixon commits suicide.
