I've never understood what significant value there is in visiting a war theater. Unless you are fighting in that theater, any short-term visitor can get that kind of cursory information by conversing with the theater's commanders. Visitng Bagdad or Mosul for a few days instructs you in very little. You would gain as much knowlege of that theater as you would of performing an operation if you watch a couple of operations.
