It is about ‘mind set’ IMO.
Old farts like me have been there, done that and are not good to go ‘a marchin’ anymore. Too old… But…
We still can and do shoot, wanna see, come in our yards and and break into our homes… Threaten my family and I’ll have taken up arms so fast you should have already been shootin…
Now if you want to talk armed forces actually invading the land… Well, ole Yamoto guy had it pegged and it is still like that. Now, if the next administration takes most of our weapons and puts us under the UN Rule and not our own Constitution, then you will see some strange and bad shit going down…
But in general, most people of the world do not understand the county folk in this country. The attacker needs to first convince people that there is no use or that they will be safe if they let the invader take over. Without that, a major population up rising in this country out of fear, or pride or whatever will make occupation a real bitch.
All I need is a creditable threat (IMO) not yours, the media’s or the governments to make me unlimber the weapons.
If called, I would go, even in today’s ARMY they are not stupid enough to put me in the actual fighting infantry, I am way to valuable and effective in other areas… But push come to shove, if I don’t have to run and jump, my target acquisition and effective fire is still pretty good.
And most importantly, as stated at the start of this ramble, I already have and am willing to again fire for effect. Up close and personal. The unwillingness to do this is the biggest detriment to war like effectiveness there is, IMO.
It is all about mind set.
YMMV
