You realize other countries have VCs too right? Yet hundreds of foreign billions still go to America because it's a better environment for innovation and produces bigger and more impactful companies. Your 3rd point even relies on it.
Note that it's per capita, and Israel has a population of 8mn, versus the US's 330mn.
I think it's pretty clear that most VC funding is given in the USA.
And note that the terms are often much better, and funding is accessible earlier. This article explicity states that you want to get seed funding in the US if you want to maximise your valuation. See: https://medium.com/sosv-accelerator-vc/what-does-seed-fundin...
Yes but these companies also largely exist because you have a deregulated market whereas the European Union is a much more regulated market.
These regulations provide for worker rights, productions and consumption safety, product quality and much more. Something America is lacking in completely.
You also have a government and department of defense that helps a lot of your big multinationals grow and kill it's foreign competitors.
You can look at the acquisition of Alstom by General Eletric as a good example.
Well that's the point. US has lower regulations and more fluid employment which leads to bigger and more innovative companies. America isn't as nationally protectionist as China though, although that will now change with this pandemic.
