You are not wrong. We are all doomed. Asteroids, Supervolcanoes, Solar Storms, Mini Ice Age, Hillary clones! Life as we know it is fragile and fleeting, It's just a matter of timing on the civilization killer event.
OTOH there are puppies. There are mad scientists out there working on cures for every ailment. I predict immortality a week after I'm gone.
America, other than very early before we'd killed all the locals, and outposts ( like in westerns ) where the locals were still fighting back, hasn't had walled cities. We're really young, and even 200 odd years ago, artillery had made stone walled cities obsolete. You can see a few Fortresses like near West Point, or Fort Niagara, even a brick monstrosity like Fort Jefferson in the Dry Tortugas, or the Shore Batteries built in WW2 that have survived 70+ years of development. But not walled cities and Keeps in the hearts of cities that is standard in Europe. By the time Western Civilization hit the Americas, fortress styles had changed to earthen ramparts and ditches. Structures that cannon balls didn't bother much, and offered killing zones for infantry. There never were cities made as fortresses after the first settlers that left their mark on the current American landscape. ( the outgrown early towns just got torn down and rebuilt. Far easier to do with a mound and a ditch than a Stone Wall 40 feet high )
This was the approach I suggested right after we freed Iraq & Afghanistan. If the Arab/Islamic propaganda machine insists that the Jihadists that kill in the name of Allah are NOT proper Muslims, then publicly agree and absolutely refuse to give them ANY consideration AS Muslims. Then firmly crack down on their financial support for the Jihadists. It's already a crime. Hammer them for every dime.
As for the " they ain't real Muslims" terrorists? An unsubtle echo of the imaginary insult of the Moro conflict in the Philippines. Where American troops were rumored to dip their bullets in pig blood to curse the Jihadists. ( there is no credible evidence this was ever actually done. It was a psychological warfare trick)
In today's world, the psych-ops can be as mild as refusing to treat Jihadists with any of the courtesy demanded for Muslims. Halal food ( kosher, almost the same ) religious texts, prayer times. Nothing. ( after all, we are told they are not Muslims ) Or in the case of military ops, the systematic and consistent treatment of the dead in violation of Islamic law. A gallon of diesel and a white phosphorus grenade. ( as an example. Otherwise no religious services or treatment )
The reason behind this is to force the Islamic propaganda organizations to either admit the Words of The Prophet urge murder & evil, or to distance themselves and their money from supporting jihadists. Because the groups like CAIR and Obama's buddies in The Muslim Brotherhood are dedicated to lying to the infidel, they cannot admit the Jihad is the Law they follow.
Present them with the binary choice of truth or punishment for financial support and they would implode.
How? Look around. Feminization is a common complaint with talk shows. My take is the same as back in 1967, when the international communist party plans for the world were read into the congressional record. Pretty simply, promote vices, divide the people and make Western civilization into an easy mark.
I do apologize to German Men. My comment was uncalled for and unfair.
The problem is a clash of cultures. Trite but true.
Most of the time life isn't "we can't live on the same planet since our goals require the other to submit or die."
But sometimes that's exactly the case. Ask a mother in Venezuela who can't buy food while the Dictator chows down in the middle of a tv speech. Or the gay man thrown off a building to his death.
Compromise with someone who demands your death isn't compromise.
It's the same with Venezuela. It's not that the Dictator wants the children to starve. It's that it doesn't matter to him. They aren't his tribe so they have no value. ( in this case his tribe is fellow socialist parasites/leaders )
My mother had the perfect solution for Afghanistan. Roll into a village, take the guns from the men, & give them to the women.
My instant vision was "Sgt. Trixie will train you gals to shoot. This is my rifle, that is his gun. This one's for fighting, that one's for fun!".
I also have a historically informed vision of the Mullahs in Iran being torn limb from limb by the women freed from their bondage. But that's going to take killing the "elite" guard that enforces their pre-medieval will. I'm good with that.
We may be hearing the oft repeated praises of English reform from slavery ( part of the mantra of the race blaming industry, that states England gave up slavery before America, ) while they auction English girls in London.
