cultural gaps are very much alive and kicking
During my career I've worked with people around the world, all in the Tech industry.
Israeli-Californian cultural gap is huge.
It is made worse by the fact that Israelis usually have a good English level, some even have an okay accent - which makes their US counterpart expect them to use the same communication etiquette they are used to.
Californians will go out of their way to avoid any overt conflict.
Israelis see conflict as a valid form of day to day communications.
An Israeli can go out of a meeting thinking he was just being told "yes", while he was given a glaring "no" delivered in the All-American-speak.
