Japanese thought they were getting into another Russo-Japanese War of 04'-05' and they would be able to dictate terms after rapping the US on the nose a few times.
Hitler believed he was already at war with the US in the Atlantic anyway despite being on the ground in France in 1918 when the US was pouring in 100,000's of troops every month.
Everybody thinks Americans are like everybody else on the planet. We are not.
From Lexington/Concord to Jefferson's "No deals" with the Barbary pirates to "NUTS"! at Bastonge - we are like no other peoples in history.
That's what vexes the libtards about guns - why don't we just fall in line like everybody else?
