Are you seriously concerned that the British will decide to invade the U.S.? 
Prime I'm sure you remember how devastating the first revolutionary war was, the US barely survived.
We just didn't have the weapons to combat the skilled British troops. All able bodied men were enlisted, farmers, cooks, store owners, stay at home dads... I'm sure you remember.
Guns leveled the battlefield.
Ban AK's and we could be in real trouble on the next invansion.
