I really liked these words from former Secretary of State Colin Powell, as said to CNN's John King in an interview:
"July 4th still represents a remarkable date for us to stall or stop and reflect on what our founding fathers achieved on July 4 of 1776," says the former general, "And the noble sentiment they gave to the rest of the world that all men are created equal and that governments serve the people. And the people serve the nation."
"So, on July 4th, let's as we were told by our founding fathers, shoot rockets and celebrate and let the bombs go off and celebrate and praise our flag," he says. "But let's not forget that the freedom we enjoy, the freedom that we declared that we would have in 1776, still has to be won every single day and it's won by all of us, but especially by these young men and women in uniform."
