While we're on the subject of the president, I noticed something really unusual. The episode starts with a bombing on Earth. Dialog indicates that the FEDERATION president announced a planetary day of mourning. I didn't notice how odd that was when I first watched the episode years ago. The president didn't announce a national day of mourning, but a planet wide one. This would be like the POTUS announcing a day of mourning for one particular state ad not the whole nation. Now, I'm sure that states do have their own days of mourning, but the local state government dictates that, not the POTUS.
Again, later that same episode the same thing happens. They turn to the president of the Federation for instructions on how to best defend Earth, get Earth's power and defense back on line, etc... Never once was any mention given about Earth's government, Earth's president or prime minister or governor. Again, this is like the POTUS dictating how to defend or help a specific state without consulting that state's governor.
