Yes - I wonder where those leaders are too. I liken it to the toppling of Saddam's Statue. That hopefully will be celebrated (again!) as Iraq's Independence Day after they (with our help) have secured their nation. Much as it took us many long years of fighting (with its defeats and misery and talk of "cut and run") to finally secure our Liberty (with France and Prussia's help).
And as I recall the wording was finalized and copies were made, but the Declaration of Independence was not signed until the fourth. (?)
OOPS - a bit off on my memory, not not signed until August:
AND - Victory was not declared until 7 years later.
July 2, 1776
Lee Resolution Adopted & Consideration of Declaration
On July 2, the Lee resolution was adopted by 12 of the 13 colonies (New York did not vote). Immediately afterward, Congress began to consider the Declaration. Congress made some alterations and deletions to it on July 2, 3, and the morning of the 4th.
