The decays $\bar{B}\to \bar{K}D$ and $\bar{B}\to \bar{K}\bar{D}$ taking into account final state interactions are discussed. These decays are described by four strong phases $\delta_0, \delta_1, \tilde{\delta}_0, \tilde{\delta}_1$ (subscript 0 and 1 refer to I=0 and I=1 isospin final states), one weak phase $\gamma $ and four real amplitudes. Isospin constraints are taken into account. It is argued that strong interaction dynamics gives $\delta_1\approx \tilde{\delta}_1$. The four real amplitudes are estimated. Some observable consequences are discussed.
