  We discuss the role of electroweak penguins in $B$ decays to two light
pseudoscalar mesons. We confirm that the extraction of the weak phase $\alpha$
through the isospin analysis involving $B\to\pi\pi$ decays is largely
unaffected by such operators. However, the methods proposed to obtain weak and
strong phases by relating $B\to\pi\pi$, $B\to\pi K$ and $B\to KK$ decays
through flavor SU(3) will be invalidated if electroweak penguins are large. We
show that, although the introduction of electroweak penguin contributions
introduces no new amplitudes of flavor SU(3), there are a number of ways to
experimentally measure the size of such effects. Finally, using SU(3) amplitude
relations we present a new way of measuring the weak angle $\gamma$ which holds
even in the presence of electroweak penguins.
