Did they call them by name in LOTR? if not I guess the US (and most of the rest of the world) would think catapult (the same way every hand gun is a glock and ever assault rifle is either an AK47 or M16)
You cant outrun the world, but there is no harm in getting a head start
Real stupidity beats artificial intelligence every time.
In the siege of Gondor the only word uttered regarding the devices is 'catapults', I believe. Even though they are in fact trebuchets, if I understand the difference correctly (i.e. that the secondary 'whip' action on the throwing arm makes it a trebuchet).
