As the twentieth century progressed, the size of the United States Federal Government expanded dramatically. This naturally resulted in the Vice President having to take on more of the responsibilities that the President simply didn't have time to take care of.
In a war you want to consider strategic points to take. So let’s say a battle takes place next to a bridge. If your army controls that bridge than you have a higher chance of victory since you get to decide who crosses and who doesn’t. Now when an army takes over an entire city, than that army can use the assets to its advantage. (Factories, roads, rail roads, runways, etc.) but when that city is the capital city, then that country loses its command and will most likely dissolve.
