I guess it's obvious by now, but I finally figured out what Q meant with this post.
Now remember that when he made this post originally, it was when we thought actions were going to take place in America that ended up occurring in Saudi Arabia (look behind you).
So, think Mirror.
On July 4th, who won their independence and from which country?
The USA did, from the UK (but, look behind you).
Think Mirror.
Who is going to get the freedom this July 4 (approximate)?
Who is the drop referring to?
The UK.
Q was telling us to have eyes on the UK.
Like I said it's probably obvious by now.
