Johnson and Zippin recently showed that if X is a weak*‐closed subspace of ℓ1 and T : X → C(K) is any bounded operator then T can be extended to a bounded operator T̃ : ℓ1 → C(K). We give a converse result: ifX is a subspace of ℓ1 such that ℓ1/X has an unconditional finite‐dimensional decomposition (UFDD) and every operator T : X → C(K) can be extended to ℓ1 then there is an automorphism τ of ℓ1 s...
