I am American, but -- surprise, surprise! -- I care much more about global stability than I do domestic policies. (I've lived/worked many more years outside the US than in the US, on every continent, and have a first-hand understanding of the impact of US policies on the rest of the world.)

But because the US still has the most influence (though waning) on the rest of the world than any other country, its domestic policies can either enhance or threaten global stability. And Trump has been absolutely disastrous -- from see-saw tariffs, to gutting USAID, to destabilizing US-Europe relations, to caving into pressure from Israel (cheered on by idiotic macho-boy Hesgeth) to attack Iran without any real plan (foolishly thinking Iran==Venezuela; do these people know nothing?). So the problem with global stability right now isn't Iran, which was a largely contained problem (despite its never-ending feud with Israel), but Trump.
