Pros and Cons of Bump Stocks?

[Jeffrey Lebowski]

So what happens when we as a nation have banned all the full auto weapons and banned and confiscated all bump fire stocks and some other country gets the idea to attack and/or invade us here and all these weapons are gone? How will we defend ourselves? A 5 million man/woman military force isn't going to cut it against a larger military force (Russia, China, etc).

I think the ship to truly ban all firearms in the United States sailed in 1776. There are just too many around.
Invading the US would be a logistical nightmare. The next world war will be drones and missiles, I’d think.
