There were six Japanese aircraft carriers: Akagi, Kaga, Soryu, Hiryu, Shokaku, and Zuikaku. In all there were about 408 Japanese aircraft on all these combined. 360 for the first two waves and 48 on defensive CAP (Combat Air Patrol). Hope this helps.
The battle of bunker hill in 1775 showed- whether the americans would win the war , so yes !
They welcomed the Americans and fought alongside them.
It looked like Europe now. But It was calmer back then before WW1
