Here's the fault in your logic: I, a 60+ year old, will not need to carry full battle rattle 20 miles.
I will only need to walk outside maybe 100 yards and cap one, maybe two, Martial Law enforcers before I die.
Times that times 1,000,000.
There is billions of young men they could bring in that scenario with a wide open border. It becomes a battle of attrition then. Sure you cap two for one that’s great. Now your house and assets are free for the next third world male who survives till the end. All they have to do is promise the survivors your stuff. If there are 20 million conservative men who go out an cap two before they get droned out. That’s only 40 million illegals of fighting age. With a full conflict here the border would be wide open and a million a month could walk over, half the battle of the next war is going to be at the border itself as the world rushes to invade it. The land and resources is what they are after the people can be genocide for all they care and that’s the plan anyways. The left is glad to rule over a land of third world low IQ serfs they want that. They keep the top rung and they have a one party system like China. The left wants to spark exactly the battle you want to fight because in an attrition war they have the whole of Africa , Latin America and most of Asia for warm bodies.
The right needs the military and our nukes to keep the world at bay and the woke mind virus has infected the military so that’s not a given. This will be the battle for Western civilization inside our borders and in the next few days. A new order is established or there is a global war unlike anything humans have seen so far. My money is on the new order is established Americans are too old,obese and soft to do guerilla warfare and with drones it becomes harder.
I was in geointel I wrote a thesis on using multispectrial assets to find IEDs in near real time from drones and other means. I hold a NGA cert in geointelligence amongst others. I extensive humint experience as well. Interrogations were my jams too. You should be getting the picture for what I didn’t for the services plural I worked with before going into pure sciences. I am an expert on the warfare you speak of I won’t post on an open forum more about it. I will say with confidence Americans lack the stomach for a Kosovo or Afghan style conflict. Western Christian values limit that. I stand firmly that the moral right has no stomach for the level of conflict needed to win a full guerilla campaign against a technological tyranny ask the Canadian truckers and more importantly a morally bankrupt enemy. They don’t have the same rules and with the muzzies in their corner you see what they are capable of with Oct 7. They would if unleashed here make that look calm against the great Satan of the West.
