Discuss the current state of political discourse in the US and the need to raise the level of political engagement and cooperation to address physical threats facing the country from around the world.
The ignorance about this country's history by its own citizens is truly depressing. We've become spoiled and lazy, with negative, petty partisanship and childish blame-game, finger pointing dominating our political discussions. Hardly worthy successors of the blessings of freedoms handed down to us, and very questionable as to whether we are up to the task of defending those freedoms. 
We all better raise our game - conservative, liberal, or whatever political philosophy alike - if we are going to cooperate in making this country work and have something of value to hand down to our children.
There are genuine physical threats to this country from around the globe. Our enemies will not be asking someone who they voted for or what their party affiliation is before the bombs explode, the guns are fired, or radiation sweeps over the land. Sounds sci-fi apocalyptic, but to say it can't happen here is to deny the reality and history of the world we live in.
