In the event that Puerto Rico becomes the 51st American state, will this result in the alteration to the U.S flag to include 51 stars instead of 50?
I'm not from the U.S, but one of those ubiquitous facts from my childhood, "The 50 stars on the Flag of the U.S.A represent its 50 states", is hard to forget.
Possible argument in favour of altering flag:
Well, if the Puerto Ricans finally decided to become an American state, it'd be prudent to throw in another star (51 states = 51 stars). Besides, it's not like adding just one star is going to be difficult (it'd be hardly noticeable anyways).
Possible argument against altering flag:
Since its just one star, why bother putting it on at all? It'd be best to avoid the bureaucratic/political mess that the addition of another star would create.
