Statement

A family of protocols that securely computes, for every $n$, every $n$-party functionality with abort against $t=n-1$ corruptions (MPC) contains, for $n=2$, a protocol that securely computes every two-party functionality with abort against a malicious adversary corrupting either party (2PC) — folklore.
