I think the tendency for isolated independence is the biggest weakness for a republic centered on the principle of liberty. Easily dissected by controlling the message at various levels. This drop was such a brilliant break down of this point. The only real way to combat that is with Free Speech. Rigorous, logic-centered debate on the public square is needed, but participation is needed for best results.

I will forever be grateful to him and his entire family for what they sacrificed, faced with what had to seem like an insurmountable series of goals and accomplishments not just for the USA and its people, but the whole world. The countless service members and civilian strategists that had to be assembled to pull this off (and sheer years of planning) deserve our unending respect and recognition. These visionaries did the impossible, and steered humanity's destiny by sheer force of will and strategy.
You are right; the defense of liberty and the greatest Republic to have ever existed is a never-ending journey, and adherence to the principals to make it work should be a constant reminder for future generations to come. We should also be vigorous in exploring the human condition for where improvements can be made in mind, body, and soul. A proper Republic would nurture an environment where that endeavor, most critical to the furtherance of humanity, can thrive without consequence. I am anxious to see where the result of the current struggles land on the conscious of the observant, the impatient, and the dissidents as the next stage in our journey begins. I am hopeful, and I pray it's not on false pretenses.
Time will tell.
