We analyse $D$ decays to two pseudoscalars $(\pi,K)$ mesons assuming the dominant source of $SU(3)_F$ breaking lies in final state interactions. We obtain an excellent agreement with experimental data and are able to predict $CP$ violation in several channels based on current data on branching ratios and $\Delta$ A_$CP$$. We also make predictions for$\delta_{K}\pi$and the branching fraction for the decay$D_{s}\rightarrow K^{+}K_{L}\$.
