As a reminder for everyone saying, "The US had never before scored four goals in a World Cup" that they mean the men's team had never before scored that many.
The women's team has absolutely scored more than four goals in a world cup, including in the final.
And they also wins things.
GW never said this and neither did anybody else. The only official symbolism in the Flag Resolution is the stars are "representing a new constellation." The rest is just an iteration on the Red Ensign, and likely the East India Company's white stripes on it. The colors have no particular meaning.
