Is it possible to invest in stock markets outside my own country? [Fidelity]

Hello,

Please bare with me here because I’m not entirely sure how to phrase this question and this may be a bit rambley as a result.

So, I have an IRA investment account with Fidelity. I inherited it with a lot of money but mostly into individual stocks. Obviously, the US stock market is crashing right now, and investing into mutual funds which include companies that will be affected by the tariffs feels like not the best move for me personally. That is the prior info needed for my question.

I guess basically what I’m trying to ask is, is it possible to invest in mutual funds within stock markets outside the US? Like, can I, as someone living in the US, use my Fidelity account to invest in a mutual fund that exclusively deals with companies that aren’t US based and won’t be affected by the tariffs directly? For example, could I access the London stock exchange? Would it be possible to use the money in my account for that? Or is my account somehow tied to the American market?

[Apologies if this shouldn’t be its own post. I’m new to this subreddit and not entirely sure on what exactly the rule on what should be an individual post exactly means. ]
