Tenuously was yours (since the original internet (in the sense of a global network) was a connection of multiple networks and not all of them where in the US, far from it) it certainly isn't anymore.
The UK had JANET in the late-70's/early 80's other countries had similar, the US was important and influential but the internet would have existed anyway, the concept of connecting a bunch of disparate networks together to form a single internetwork is one of those things that would have happened anyway.
There are 5-6 times as many users outside the US as in the US, most of the equipment running it isn't even made in the US anymore.
So far the arguments I've seen on here have been "well we set it up so it's ours forever" which by that logic means we own all the telecoms systems in the world (we been the UK) as well as all the railways.... (which is absurd but then so is "it's ours" in relation to the internet).
That model doesn't work when we all share the same root name servers. I don't want a majority vote of a bunch of oppressive countries to be able to strip a website of its domain because it has an offensive joke on it.
The US have been good stewards so there has never been a reason to seriously contemplate moving en masse and without that critical mass you'd end up isolating your national network and having to bridge out anyway.
That said there is essentially zero technical reason why we couldn't just route (pun intended) straight around the US 'control' of the internet if we wanted so yeah it's a case of "we'll let you run it as long as you behave" rather than "you are the only ones who can".
