Nominalization of Conditionals to Use With 気がつく (realize)


First question on this Japanese sub-community. Sorry if this confusing or hard
to explain. Basically, I want to say

> Everyone should realize that if the YouTube thumbnail wasn't a picture of an
> anime girl, there wouldn't be 1 million views.

but get stuck on "that if". I'm not sure whether to nominalize the conditional
part before adding in 気がつく (realize), or something else. Wasn't sure where to
put the "realize" phrase, but here was my best shot:

> YouTubeサムネールはアニメの女の子の写真でなければ１００万視聴回数がない気がすべきつく。




You can say ことに気が付くべきだ or のに気が付くべきだ.
