I am from Europe and I am also not happy about these results. Minority rights are one problem, but it is also things like support for Ukraine or general state of democracy in the US, since US has always been seen as a big part of free and democratic world.
However, if I should find something positive people could use to cope with this situation...Republicans already had all three, the White House, the Senate, and the House for the first two years after Trump won in 2016, and the only major thing they did was to pass tax cuts for the rich. I think that the party will make, if anything, bad decisions on economy, or let's say, healthcare, and pay the price for it during the next midterms. Then the Senate might flip and Trump will not be able to do whatever he wants anymore. The midterms usually do not go very well for the party in power, and that is what happened in 2018 as well.
Also, it is not like Republicans have huge majority in the Senate, for example. When it really comes to making specific decisions, some of the Senators might revolt because the decisions would prove to be hugely unpopular. I would still like to see how things go in 2025.
