I said partly. Regarding the internet the US had a central role in developing and implementing the technology and infrastructure, as is testified by the fact that our current domain system is still US-centric, but in a sense they did not invent it.

Regarding defeating the axis and specifically Germany (Italy was not a military colossus) there is data that shows that the USSR had a bigger impact in defeating the nazis.

No one denies the contributions of the US in both of those feats, but also it is undeniable that the narrative isn't always factually true.
