It doesn't really bother me that the Russian plan for Syria probably won't work. The plan to bomb Syria to punish it for chemical weapon use almost certainly won't work either. Neither option will solve the problem of Syria's chemical weapon stockpiles.
Because of our over-optimistic estimation of what military force is able to accomplish, we don't seem to evaluate American strikes on those terms. When we must DO SOMETHING, it is presumed that SOMETHING means military force and that military force by definition gets the job done. All other options other than military force have the burden of proving that will solve the entire problem. For military strikes, that is just presumed to be the case.
