I don't agree. It's stretching things to call the COVID19 fiasco a 'war', however costly in lives it has been.You need to up your standards for CiC.
His tacit approval of foreign dictators while shitting on and abandoning allies like the Kurds? Assassinating military leaders of countries we're not at war with? Outright threats of fire and fury when he felt slighted? Surprise unilateral pullouts with zero notice for allies from the child king of bad faith negotiating? He has gotten us into war, it just hasn't started yet. FWIW he got us into a war with covid, let an international crisis become a domestic emergency where 9/11 body counts happens daily. Still prefers to play golf rather than show up for the fight, I guess just Cadet Bonespurs showing Vietnam isn't the only thing he can run from.
Using the term 'positive' towards anything in the foreign policy record of the Trump admin is, quite frankly, pretty fucking baffling. He has asked his underlings for war on a few occasions IIRC, thankfully to be talked out of it. The credit you want to give should go elsewhere.
And, sure, his foreign-policy has been inept, and he _risked_ war with Iran. But it didn't happen. And compared to the disasters of the Afghanistan and Iraq wars, I think that's something to be thankful for.
I do think one could say his one saving grace is that he's an abject coward. He's scared of getting into a war. And not necessarily because he fears being shot at himself, but because (as a narcissistic, shallow, showbiz guy who knows very little about geopolitics and the world outside the US borders, and still less about any kind of sacrifice for something greater than oneself) he feels out of his comfort-zone and knows he'd be quickly sidelined by others who would display more authority in a war situation.
He could definitely have been worse, in other words.
