The numbers matter because they make any footage you could take into a footnote.

No one would care about Pearl Harbor if prior to it the Japanese had somehow destroyed half of US harbor the week before.
No one would care about 9/11 if prior to it terrorist somehow found the way to methodically set fire to half of New York the week before.
And those are remembered as the INITIAL ATTACK.
"Operation British" would only stand equal if instead of nuking 100+ colonies Zeon had started with only this colony.
That's why it is a case of "Author has no sense of scale but wanted it to be impressive" and we have to make up our own canon to fit the narrative they want.

Also we are ignoring that according to maths I saw, a space colony wouldn't be enough to create a crater that big.
