Here is my two cents worth regarding your theory.

Russia would get Alaska (they owned it originally anyway and about a year and a half ago Obama gave them back 7 Alaskan islands).

China would want Washington, Oregon, and northern California.

Then, try to visualize yourself not on your porch defending your family, but somewhere in a very rural area which is off the beaten path.

It is way past the time to get out of thr cities.

I really feel that putting as much distance between you and the "hoards" and being out of sight, not right on a main road, is your best "defence" for what is coming down the pike.
