This is pretty much my thinking as well. I too have a family, and while I'd prefer they never have to experience their world torn apart like that, if it's inevitable then I'd rather it comes while I'm best prepared to protect them and fight back i.e. the next decade or so. I'd hate to be sitting there at 80 years old and have my son have to do all the dirty work because I'm too old.
Not mention with the wars of the past decade coming to an end (whether they should or not) we have a massive amount of GWOT vets with recent combat experience in urban and rural environments a chip their shoulders.
Now would be an excellent time.
